I picked up 5 tiger barbs about 2 weeks ago to get some dither action. Yesterday I noticed them flashing so i started to dose with prazipro. Today only one of them is acting strange. It has already leaped out of the tank once so i have it in a net in the tank right now so it doesn't leap again. Before and after it jumped out of the tank, it wad hanging out around the top, then look like it was getting spooked. Now all it does is try to jump out of the tank. Any ideas?
