I think one of my fish is sick

[rob0147]

Hi there

I have 3 tiger barbs in a 20L tank. 2 of them look fine, darting about in the water chasing each other, etc, but one of them is very listless. It's hangs about at the surface of the water at a 45 degree angle (head up, tail down), then it will just "sink" itself back down to the substrate now and again. I've only noticed this today and I'm not sure whats wrong. It doesn't look very happy at all.

Any help and advice will be great

Have the other 2 bullied it? Normally you'll need at least 6 Tiger Barbs to even out the wear and tear on the subordinate fish.

It's quite possible that it has been bullied. The bottom half of the caudal fin looks damaged compared to the other two fish.

Maybe I should have got 6 tiger barbs, but I don't think my Tank would hold 6


Thanks for the info LL
