Why are fish staying on bottom of tank?

Answer 1

They are possibly down there because the water is too warm in the higher levels or it could simply be that your water is bad and needs changing. My advice is to do a large (80%) water change ASAP then remember to do at least a 50% water change weekly.

Answer 2

Maybe the water is too hot or needs changing. Fish can go to the bottom for either reason. If the fish are not tropical and the water is above 75F heat could well be your problem if not then your problem is bad water conditions. My advice is to change the water ASAP. Then read the following basic rules of fish keeping and follow them. :- 1 inch of fish needs a minimum of 1 gallon of water. :- Every fish tank needs a continuously running cycled filter. :- Every fish tank need at least 50% of its water replaced every week.

Answer 3

Goldfish have central mouths. They are not bottom feeders or top dwellers. This means they should stay at the center of the tank. It also may mean that your fish are sick, or they could just be scavenging for food in the gravel.

Answer 4

The fish has swim bladder disease. This can be helped, however not cured. I had the same problem with a fantail goldfish, this fish has been alive for three years with swim bladder, and is still living. If the fish does not get help, eventually it will die. The way to help this disease is to give a frozen pea to the fish, and make sure it is peeled. If this is a large fish, one pea will not work. Two peas will do the trick, but smaller fish only need one. Hope this helps!

Answer 5

Maybe the bottom of the tank is cleaner? You should go to a place that sells fish and ask them. Good luck:)

Answer 7

Most of the time its because they are resting. But if it stays there to long its probably dead
