I have 6 tiger barbs total ( of different varieties). I noticed lately that one of them doesn't look very good. He is looking extremely skinny, pale and in never with the group. They are in a 29 gal
tank with some other verities of fish. All of which are healthy. My permitters are all good. The only issue is I am currently treating my tank for ich so the temp is set high. I'm thinking that the barb may be the low man on the totem pole in the group, although I haven't seen them picking on him.
Any help would be greatly appreciated.
I'm thinking mab adding a new barb may help from what I have read.
