fish swimming upside down

Recommended Posts

We have a small indoor tank (about 25 litres) and we have 2 out of 3 fish that regularly swim upside down. They dont seem to be distressed, and seem to switch modes with gay abandon. The third fish swims normally. Has anyone else come across this ??


The two best times to go fishing are when it's raining and when it's not

Wotnob,

 

Strange indeed (but cool if they are healthy. I don't know much about fish other than cprinid. If they swim upside down they almost always have an air blatter problem or chemical poisioning. (I don't even know if all fishes have air bladders?).

It's likely to be a swim bladder problem; often caused by overfeeding.

 

Starve them for a week and see if it stops.

We went through all the remedies, including feeding frozen peas, but to no avail. They seem happy enough, even doing barrel rolls to change position at times :rolleyes:
