Soo I have a 50 gallon tank with 2 large common goldfish I've had for about 3 years now, 2 black mores, 1 pleco, 1 blue gourami, and a very small common goldfish I got recently. My problem is one of my larger and older goldfish has been laying on the bottom for 3 or 4 days now, and he won't eat. He looks beautiful and he'll perk up and shush the other fish away if they get too close. He'll tolerate the other large one sometimes but for the most part he's just been laying on the bottom and against the side of the tank. All my other fish in this tank seem to be right as rain. Is there something wrong with my fish or has he just become territorial?

    He may be constipated. Try feeding some peas. Constipation will make them behave like that.

    He's moveing around a little more since I posted this but I'll give it a try anyway, just regular old peas from a can?

    Hi just a little of subject. I have a question about your fish, we recently had to start over because we brought a fish home and it must have been sick and it died four days later and then our common goldfish which we had for 4 years died 9 days later. Anyway my question is I notice you have common goldfish along with a black moor. I have been reading they don't make good companions because the common are much faster and at eating time the common get most of the food, how long has yours been paired in the same tank and do you find this to be true or do your slower fish seem to get enough to eat?
  • Bill - 2012-06-08
    HI, not sure if your fish is laying on bottom because of a illness, but as my previous ,comment we lost our very active,(3) beautiful 4 inch common golds due to an illness. First signs of our fish being ill was their back fins were not up like usual but layed down on their back and they layed on the bottom most of the time until they passed with occasional movement. Ours later developed tail rot so that may be something to look for, you might run a water test to check levels, petco does them for free if you don't have the equipment, sometimes high amonia levels cause fish to act this way and need to be corrected asap with water changes. Good luck!

I have a Common Goldfish. First I thought I had a Comet Goldfish, so then I named it comet. I have my Common Goldfish with my Shubunkin Goldfish and my black moor fish. Their name's are Madea and Obama. Thanks to this web site, I learned more about all of my fish. Thank you all so much.

    Just a quick question for you, we recently started our tank over due to having a sick fish and then his sickness wiped out all our fish, anyway my question is I noticed you have a slower fish (black moor ) with your common fish and shubinkin. I have been reading online its not a good idea to combine them beacuse the faster fish get the most of the food and then slower fish don't get enough to eat. How long has yours been combined and do you find this to be true?

    Well really if you had a disease fish take out all of the other fish as soon as posible and I have a 1 gallon tank and my goldfish is happy!

    The lionheads and comets do not always mix well. Normally it is hard for a lionhead to catch the much faster comet. If the tank is big enough it will be fine.

I just hope you will get lucky with lucky because I just went through a lot of the same thing with my little goldfish. Sadly we lost the fight. We had most of what you had except I did not think we had droopsy. Mine was a 29 cent fish food fish also. We had 2 of these guys the other seems O.K. for now. Mine had popeye and never got rid of it and he was blind but seemed O.K. Last week he got fin rot. I just changed out their tank (washed rocks, a no no) and all of a sudden he was in his last hours sitting on the bottom and couldnt stay up right. He went over within 24 hours so it sounds like you may have a better chance if yours is lasting this long. My heart goes out to you and it sounded so much like what happened with ours . Have you checked out fish T.B. he sounds like this might be whats up. From what I read he might be able to live for a while but I do not think there is a cure and after they get so weak adding to much meds and total water changes are very hard on them. I will say a prayer for your baby and let us know if he starts doing better.

I live in Hamburg, Germany where as for Fish lovers there are many different types of fishes that can be kept. This includes freshwater Sting rays, Piranhas, Catfish & also South American Discus, I have also bred Racing Pigeons & have had Himalayan Parrots in the Past. As for any animal keeper one must witness how Kobe a region in Japan Treats their Livestock's & the result is good Steak :-) Well I do not slaughter my pets for commercial purposes, I adore them like my own Family member & cherish those Peaceful moments with them. Pets are not meant for human neglect & abuses they must be treated like your own Progeny's. So a callous & irresponsible person must learn how to maintain any Pet instead of manhandling it, THE TIP always think & learn about it & then plan systematically before you Purchase or even adopt a Pet. It's like you Drive your vehicle but do not know anything about its maintainability, Ignorance is chaos and chaos is sheer Disaster & risk for others!

Always Turn off the Filters & Oxygen pumps when Feeding ;-)

    For flake fish food it prevents the food from getting swirled all over the aquarium and sucked into the filter where it is wasted. Just make certain to turn everything back on after they have fed.
  • Jimmy Thai - 2011-12-30
    That's what I do too! It's because I feed them flake food, so whenever the filter goes off they always think its feeding time :D

I have 4 common goldfish and just noticed that one of them has this white bubble growing on its head. It does not look like it has puss in the bubble unless it has already popped. I need to know, should I take this one out of the tank so that the other 3 do not get what this one has? Is this treatable? The other 3 fish are about 5.5 to 6 inches in length and the one with the bubble on its head is only about 2 inches and they were all put into the tank at the same time. I do not want to loose these fish so can someone please help me out?

    Without more specifics, there is no way for me to tell. Could be ICH or something called Hole in Head.... there are several things that sound like white sore or white mark. Attached is an article on Fish Disease and Treatment. Clcik on it and scroll down and it lists the various symptoms and recommended treatments. It is pretty informative and yo should be able to tell what your little guy has from reading the symptoms. Let us know.
  • Clarice Brough - 2011-05-09
    The first thing that comes to mind is a fungal infection... which looks like a cottony patch, usually rather grayish or white. You could isolate him until you determine if it is an infection just to be on the safe side.

I started with 14 Gold Fishes since 2005. Till now they have grown huge. I have also bred of course in my aquarium. Tips always use the best canister Filter,Water conditioners,Chlorine,Nitrate, Broad spectrum medicines, Ph/Kh Neutralizer. Use ultra violet bypass in the water outlet and give them plenty of oxygen via pumps. Change water after every 15 days. Feed the baby frys after the eggs have hatched with crusts of dried up small shrimps and add them back to the aquarium after they are year old till then keep them separated in another tank running on medium speed outside filter and of course oxygen with water treatment drops. Always add the collected eggs in the right Temperature Tank 25c will do till they begin to hatch. I feed my adult Gold Fishes with small shrimps soaked in water before feeding about half a small cup 2 Times a day. And when I add broad Spectrum Medication right after water change I then turn off the Ultra Violet bypass for a day or so. Filter cleaning is also necessary during the change of water in the aquarium. Make no Compromise with Maintenance and I bet you will be rewarded. LOVE THY NATURE and BE BLESSED!

I must say I have learned a lot with "Lucky" my goldfish. He was my starter fish. Well him and two others. But two died. They got sucked up into the filter. Yap...learned my lesson on that one. And truth be told that is how Lucky got his name. He was the only one left. So he was.... lucky. We started him out in a 20 gallon tank. He has had filters, heat and bubbles from day one. Now he is in a 120 gallon tank all by himself. He is about 8 to 9 inches long. Lucky is almost 13 years old now and on January 10th 2010 we noticed he was not his normal self. It is now January 26th 2010 and we have done and are still doing EVERYTHING we can possible think of to help make him better. His symptoms are: laying at the bottom of the tank, pop-eye, trying to swim but he ends up on his side. He was bloated, his scales where protruding and had not went poop in sometime. So we have went from Constipation, to Swim Bladder Disorder, to Dropsy, to Septicemia. And NOW I am at a loss. We have done so much, water changes of 20% or more, at one point we did a complete water change removing all the old rock with new. (He really loves new water)It has been a roller coaster ride with him doing good and then he goes back down-hill again. We added Aquarium Salt to his tank as suggested by a pet store to help pull out the fluid that was causing the bloating. That worked cause now he is skinning. Scales are much better he looks normal again rather than a pine cone. He is starting to now show black spots on his scales. I forget what it was called, but they stated that it is a sign of the fish's body healing itself. He still is very weak. Not swimming around and not beinging able to stay up straight. We have been hand-feeding him for about a week now. It was to the point to where he was laying on his side and we where having to pick him up by hand and lean him againest something, because he couldn't get up by himself. And today was the first day that he has actually trying to chase my hand. (it's cute) it acts as if he is starving. Tonight he has been able to sit up by him self for short periods of time and is becoming more active. He has also got on his side and got his own self up quite a few times tonight without our help. But he is still no Normal Lucky. He swims slowly, and only a inch or so at a time, then he stops and takes a break. He is always at the bottom of the tank. He hasn't tried to swim up in a week. Also I seen about 2 days ago a clear like string about an inch or so long with almost hair like things on it floating in the tank. The tank was just cleaned 100%. And then tonight he was resting against his ship and I went down to feed him and there was this long string like thing that almost looked like feces, but it was red and brown. We have treated him and his tank with Maracyn-Two and also a Gel-Tek Medication Food with Tetracycline. That treatment was completed almost 36 hours ago. At that time it called for a 20 % water change, but with the tank water beinging a yellow color and Lucky doing VERY bad, I decided to do a 70% water change. It has been a little over 24 hours since his water change out. He is showing an inprovement tonight, but I hate to get my hopes up because his health is always changing. Tonights testing showed the Nitate levels at 20ppm. and the Ammonia leavel now is 0.25 ppm. We are trying to get them back down to 0.0 ppm. We have been checking for PH levels as well. Ph Looks good. But does ANYONE have any sugguestions??? Is there something I am missing? Lucky is our pride and joy! With his very own personality! This fish has been through a lot over the years, putting up with us as newbie fish parents. I have to do all that I can to help him. So please if you know of anything, Please help.

    I am an owner of two common goldfish. I want to help you. Even though I am 12. Are you putting water conditioner in your tank regularly? If not, you should start soon. 13 years? Dang he's old.

    Try buying another goldfish. That might help. Maybe he's lonely.
  • Erika - 2010-10-02
    I looked at the part where you talked about him swimming on his sides! This mostly happens because when fish eat pellets, they expand in their body, this blocks their bladder, making them unable to swim correctly. If I were you, I would soak the pellets in water for about 5 minutes before feeding them to Lucky, that way they don't expand in his bladder. Also, constipation are signs of the pellets expanding in his body. Do not pick him up by hand, if you don't have to! Picking them up by hand can cause infection! Since he is pretty sick right now, his body wont be able to fight off infection as easily. The hair like things could have been caused by mating season. Males get hair like things over their fin and head. Long feces can be caused by over feeding. Good luck with Lucky! :) Please, reply back and tell me how things are going with Lucky! I hope my reply hasn't been too late. :( Try taking him off pellets, or soaking the pellets in water for about 5 minutes before feeding him, and don't feed him too much! Goldfish are the type of fish that, if you put food in the tank, they will eat it whether hungry or not! Too much food causes long feces, and make them more prone to sickness or infection. Try these things for a few months, and if they aren't working, tell me and I could give you a few websites to look around on. I hope things turn out okay with Lucky!

    I wish I knew a way to help your goldfish. It might be dying, or it may have some kind of disease. Have you checked with a veterinarian to see what the problem is?
  • \"Violet\" - 2010-10-10
    What food are you feeding Lucky? Grains or Flakes. We had a fish for 17 years, and we didn't even have a filter, or an oxygen thing. We fed him the little grains. I recently got another fish, after our old one died, and I fed the new one flakes. He died 2 weeks later. I don't have a scientific reason, but since then, I have had 10 fish, fed on Grains, and they are all still alive.
    Good Luck.
  • Nick - 2010-10-12
    I hope Lucky is doing well, I have had this problem a few times, overeating I think was the cause..

    You say you changed all the rocks and water you probably got new tank syndrome which won't help an ill and weak fish
