I have a 20 gallon tank that is heavily planted and has plenty of hiding places. So when i bought the two blue barred barbs I didnt think much of it when they started chaseing each other it would alwasy go back and forth and the owner told me that they do that usually that it was just somethings most barbs did. But a couple of months later and today i noticed that one of the barbs isnt moving as much and looks smaller the the other one around the tail area as shown in the pictures. I read more into them and it said they are timid and peacful fish and show little aggression but like to be in groups of 4 or more. Is having only two in there bad for them?
