Goldfish won't swim??

[smedley]

Hi,
I'm new to the boards. We have a 180 gallon tank, with 3 fantail orandas.
1 of the fish is fine, swimming around and feeding as normal, but the other 2 have started laying on their sides on the bottom of the tank. They can still swim, as they will get up and swim over to eat, but do absolutely nothing but lay the rest of the time. Can anyone shed any light on what could be wrong with them please? I'm kind of at my wits end as to what to do, there is a filter and aeration system in the tank, and they don't appear to be diseased.

Thanks in advance.

Smedley.

No suggestions? Anyone?

[Fish Friend]

do they have a fat belly ? can you put a pic on here and give us your water parameters, that will help us alot to finding out whats up with the fish...

Telling us your water parameters would help.

Ok, will try to take some picture tonight and post them, water parameters? I'm not sure what you mean by this? Yes they are the fat bellied variety of fish though.

Water paramteres, y'know, nitrates, nitrites, ammonia, ph etc. Use test kits.

[Fish Friend]

yeah.... water parameters are your water readings.. like comham said, pH, GH, KH, nitrates...blah blah blah ...

[Fish Friend]
