Strange Tiger Barb Behavior!

[kevinjames]

i have six tiger barbs in a 130l tank. all seem very healthy but found some acting perculiar. they seem to hang vertically with their mouths pointing down and seem to shake all their fns at the same time. at first i thought the worst but they seem to be fine afterwards and have been doing this for nearly a week now. can anyone shed any light on this strange behavior???

Shaking of fins maybe could suggest breeding behaviour - like with cichlids?? I really don't know.. probably best to ask in the Cyprinids, Characins and Atherinids forum - the people there will know for sure.

I have 1 that does that, i think its normal, its probably relaxing
