I have had my bala sharks for quite some time now. They are around 1.5 years old.
They have developed a weird habit, and was wondering if someone would be able to help me...
They will swim to one panel of glass and just swim up and down it, with their nose touching it, for hours. Not moving for anything..
Why would they be doing this? Should I be worried?
