hi have a question as its confused me as to why this fish has died :S we have a tank that has just two goldfish in, the previous fish we had lived 10 plus years, after they past we didnt have any for awhile but then ended up getting one from a fair (which is bad i know!) and from a pet store. we have had them both nearly 3 years ones grey (pet store one) and ones gold and white (fair one) now my mother decided to buy some snails and a mussel for the tank too and some plants to go in it, the grey fish just kept eating the plant and the gold one wasnt bothered by it at all. the next morning the grey had gone really light in colour just overnight, so we took the plants out, but the grey was constantly at the top as if gulping for air whereas the gold was just swimming about normally it gradually got worse so changed the grey to another tank incase there was something affecting it in the tank it was in, it perked up abit but afew hours later it passed away now ive tried to research what could have caused it as i was thinking it could be eating to much of the plant but alot of sites say the goldfish wouldnt eat until it will have eaten way too much :S then i thought maybe ammonia levels in the tank because of the snails but the other goldfish is fine and healthy or could it be something else but that worries me it could affect the other goldfish any ideas/help?
Fresh water mussels are filter feeders and it is unlikely that one would get enough food in an aquarium or bowl. The mussel won't tolerate medications of any sort and they need very clean well oxygenated water.
From what you have said I suspect that the mussel has died and caused either the ammonia or nitrite to spike as well as lowering the oxygen level in the water and this in turn has killed the fish.
Fish are individuals like us and they have individual tolerances, just because some fish appear to be fine doesn't mean that there isn't a water quality issue. The only way to be sure is to test the water or to take a sample to your local fish shop and have them test it for ammonia and nitrite and pH. This should be done as soon as possible.
ah the man at the aquarium shop said a mussel would be good to filter the water, i dont think its died as its shut (think they open when they die?) im thinking it was the plant as the grey was going crazy eating it but the gold wasnt bothered with it at all. so if that man at the shop was wrong about the mussel, maybe he gave me the wrong plant?
It is very unlikely that the plant had anything to do with this, goldfish naturally eat a large variety of aquatic plants. Plants which are toxic normally have a very bitter taste to deter the fish (and other things) from eating them.
Generally speaking it isn't a good idea to take advice solely from someone who is profiting from making a sale.
Mussels are filter feeders but they won't improve water quality and they have very specific requirements and they aren't suitable to be mixed with goldfish.
Hi there, ooh lot's of questions lets hope FK can help
we have a tank that has just two goldfish in, the previous fish we had lived 10 plus years
Common/single tails are pond fish and are not suited to tanks. Given they get to over a foot long, they are outside pond fish only. Fancy goldfish get smaller about 8 inches or so but put most of this growth on in years 1 and 2. 180/200 litre tanks with external filtration will house 2 mid - long term.
Big difference in thriving as opposed to surviving.
after they past we ended up getting one from a fair (which is bad i know!) and from a pet store.
Commons or fancies? Please clarify?
we have had them both nearly 3 years ones grey (pet store one) and ones gold and white (fair one)
Both should be more or less fully grown. Stunting can occur of course, if fish are kept in too small a tank, please clarify.
