Ok.... You are all freaking me out! I bought 3 little goldfish (they were babies, tiny and black) for my 5 gallon fluvial chi tank. My two young daughters loved my male beta and when he passed after 4 years, I thought I'd quickly replace them with these 29 cent feeder fish. It is now four years later and these fish are huge! Two of them are close to 4' (before the tail) and the third is about 2'. I feel bad as they are in such a small tank (I read here they need 10 gallons per fish?!!) but there is no way to get such a large tank to fit anywhere. Since they have already thrived so well for 4 years am I harming them by keeping them in a smaller tank?

    You stunt their growth, cause stress and they will get deformed eventually, from trying to grow. You have to get a bigger tank or give them away.

    You really should get a bigger tank. 10 to 20 gallons for them would be good and actually give you and your kids the ability to enjoy them acting more like they are suppose to.

Can I put feeder goldfish in my community tank?

    I would not recommend this.  Feeder tanks are normally full of disease due to the stressfull conditions and over stocking.  Goldfish produce a lot of amonia which can cause issues with your other fish.  They can also  get large ang nippy very fast.

Please help my fish's scales are falling of. What's that about, is it a disease or something?

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.

    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.
