Do goldfishes mouths and gills still move when they are dead? My fish keeps lyin on the bottom of the tank belly up; he is very fat and I've done everything that is suggested online including giving him a bit of a fresh pea! Nothing seems to work.
no nothing should move and I believe they start floating if they are dead. If it is gulping or its gills are still moving it is still alive.
How large a tank is it? Goldfish need at least 10 gallons of water EACH...
Do you have a filter in it? Goldfish are notorious for creating a lot of waste and you NEED a filter.
Has it undergone a nitrogen cycle?
Do you condition the water to get rid of the chlorine and other toxic substances?
Have you changed anything or done anything to the tank recently? (added decorations, done massive water changes, put in new fish?)
How much and what do you feed the fish? do you remove uneaten food?
Did the fish show any signs of illness prior to this?
If you answer all of this we should be able to help you.
A 25% water change may help though...
It's in a 21 ltr tank.
I treat the water.
I have a filter.
Don't know what a nitrogen cycle is.
I change the water regularly. Nothing else has changed. He was very fat and having looked at the internet I gave him a quarter of a pea but it wasn't looking too well changed the water as instructed.
Thank you for your help.
Two reasons your goldfish is ailing.
1) you tank is too small. Goldfish are notorious for producing a lot of waste. Your first goldfish needs at least 20 gallons (75 liters) of water and another 10 gallons for each additional fish. Your 20 liters is only a little over 5 gallons. Your filter will not be able to cope with the quantity of toxic compounds that are building up due to the size of the tank.
2) your tank has not undergone a nitrogen cycle. This means there is high ammonia and nitrites in your tank...both toxic to fish. Read this to understand what happens to new tanks to make the water safe for fish.
Basically new tanks develop three kinds of bacteria. The fish waste and unbeaten food create ammonia. One kind of bacteria develops that eats the ammonia and converts it into nitrite. Then another develops that converts the nitrites to nitrates. Your tank water is safe for fish only when the ammonia and nitrites in your tank measure 0 and the nitrates less than 40 . This process can take 3 weeks or more....
If you search the forum with keywords like goldfish lying on bottom you will find that many of us have been in your shoes. Unfortunately pet shops perpetuate many myths about fish.
Increased water changes are bound to help if your fish is not too far gone. Goldfish are very hardy so don't give up on him ...
