i know this is the comment area but i need some advice, i have a 20 gal tall tank, was given to me for free, and i currently have 4 small shubunkins in it. i noticed that they arent swimming that much and dont seem to respond to much when the food comes in. any ideas what this could be?

    Hi Erik, we also answer questions, its okay. Has the temperature dropped? Most fish are not as lively or hungry in the winter if the temp of the tank drops abit. Other things would be inadequate biological filtration resulting in ammonia or nitrite. If the aquarium is new (less than 6 weeks old) or has been thoroughly cleaned recently, you could check for ammonia with an inexpensive test kit from most any pet store. Hope this helps!

    I finds it funny how people argue about what size tank you keep your fish in. I know this will probably bring some bad comments but I got two small fancy gold fish, three rosy barbs, three guppies and two bristlenosed cat fish in a 35 litre tank and they seem to be fine the gold fish and rosy barbs were originally in a 21litre tank but they still look small now in the 35 litre tank compared to the size of the tank and they haven't really grown a lot at all. The 35 litre is the only one I can fit at the moment and the only one I can have because I still live at home with parents but dad thinks its big enough for them and his been breeding fish for years. And freaky of it is so bad why isn't it illegal for pet shops overcrowding the tanks as they are suppose to set a example. I think if you want a fish you could try experiment keep the advice handy but isn't that how you get experience trail and error who knows the people my be wrong and you could surprise yourself. The same thing could be said about dogs trust me because I'm a dog groomer why get a long hair dog when your going to shave its hair off and people do it would be easier just to get a short haired dog or why move into a house that doesn't allow pets when you have one you wouldn't get rid of your kid if they were not allowed.

I have got to shubunkin fish. I got my water tested they said it was fine. I got a bottle of tapsafe just in case the man said it would do no harm, I have a filter in tank and I fill water and let it sit before I put it into the tank. I leave some of the old water in the tank, I hear people saying add a pea to tank why do that does it help in some way in a newbe with fish could someone tell me about this pea?

    Congratulations on joining the fish keeping hobby, you'll have lots of fun. For goldfish, people feed frozen peas to help with swim bladder problems. You most likely won't have that problem with a Shubunkin however, as its more common with the varieties that are more balloon shaped rather than streamline shaped. The Tapsafe is to help condition water, basically that means remove chlorine and chloramine that is found in tap water (but is harmful to fish). Do regular water changes, as goldfish are pretty messy, and have FUN:)

    You really can't tell the difference with great accuracy.  However, when they reach maturity the male looks thinner than the female.  During breeding time, the male will get white sorta (looks like salt) prickles on his head and gills.  If it lays eggs, it is a female.

I have a Shubunkin who has all of a sudden gotten very fat. I'm not sure if this means eggs or constipated or ill. I have 2 other Shubunkins who are not at all like this. I'm quite concerned. Anyone have any suggestions?

    Good start. What you need to do is ask questions - here is a good place and I expect folks will answer you. Also, read - read the above article and anything else you can on Goldfish and Shubunkins in particular. People will have some helpful hints and the Animal World article above provides you with all the basics.

I have 2, 1 1/2 inch shubunkins, about 1 year old. Their tank gets very stinky within 2 days of cleaning it and I make sure it is clean. Partial water changes do no good. Could the filter be too small for the tank. I bought it at the pet store, says great for 2 fish. I need help for Birdman and Lil Wayne !!!Thanks for your time :)

    Because the filter says 2 fish - it doesn't mean it will work for your two. Shubunkins have a lot of excrement and will dirty the water faster. They are goldfish and they have no stomach so what they eat comes out after the use the mainerals to maintain themselves. Two fish - maybe two guppies or two tetras but goldfish including your shubunkins are different.

    You may also want to look at getting ammonia bags for filter.
  • Jeremy Roche - 2012-03-17
    They have drops you can get if it is an algae bloom. If that isn't it, try a bigger filter. Maybe over feeding?

    My shubunkins are realy small and have been that wat for months now , I also have a medium comit at about 6cm. I recently lost some fish after an infection after I purchased a fish from a pet shop.The fish I have now suddenly seem weeker but I treated the water with medicine so they didnt get the disease and did a 70% water change.They are swimming slower , going to the top a lot (but the water is well oxigenated) and sometimes lying under the fillter ( which is working well).They aren't\t folding there dorsal fins and don't appear to have any other symptoms. I'm baffled as to what is wrong. Does anyone know what the problem could be and how to treat it.

    That happened to me , it is probably a algi problem in the water.Icoverd my tank for 2 days and let in no light then did a 20% water change and it cleared right up.

    It sounds like there is not enough oxygen. They will go to the top and gasp for air when there is not enough oxygen. Increase aeration, either surface movement with a powerhead or more bubbles with an air pump. A partial water change might help as well.
Blob - 2012-06-11
My shubunkin fish has like a see-trough blob on his tail and his tail is kind of crooked although Im not sure whether this is because it has this boble on his tail. Otherwise seems fine. Been on holiday so might be stress. Please does anyone know what's the matter?

I have a shubuckin. It shares a tank with 3 koi. The last few days my fish has just been at the bottom of the tank not moving. He will move around to eat but after he goes back to the bottom. He usually is a very active fish. Can anyone help me? I'm worried

    My pet shibukin stays at the bottom too, after I have cleaned his aquarium. Yesterday he was fed a lot that he had lots of 'popo' in his aquarium. The water become yellowish. I'm worried that I forgot for about 2 weeks to clean his aquarium which may be add to his inactive routine.The rooms temperature too, risen up to 36 degree. Please help me about this.

Our 4 year old shubunkin goldfish is very swollen in the sides. We thought it might be pregnant, but it has been like this for a long time -several months. It seems active enough and is eating well, but we are concerned about it. It shares a large pond with a koi carp and other goldfish. Our other shubunkin was killed by a heron last winter. The pond is now covered by a net.

    Sounds as though it is constipated or had a bacterial infection. Try to obtain antibiotics you can inject. Caution; I brought one fish to the vet but the stress of the visit killed him so I don't recommend that. It is also advised that you isolate him into a 10 gallon "hospital tank. Prepare the water and let sit for one day if possible before you transfer him. Feed him defrosted frozen peas. Any or all of these measures may save him. Good luck I get attached to mind and have had them over ten years but lost 2 in past two years to similar problems because I didn't know what to do. They are also social so try to get him a shubunkin friend. I noticed my surviving patches became despondent until I repaced his friends with two new shubunkins.
