About a month ago I purchased 5 tetras and 5 tiger barbs. The first one to go was a tetra who I have yet to figure out who killed it. Then I found a tiger barb floating, but it was gasping for air. I put it out of it's misery. Now, I'm starting to notice another barb shaking but it's swimming slowly. Doesnt appear to be dying or anything, but it doesnt look good for it.
what could be the problem? It's a 20g tank and a total of 8 fishes. Tests for ammonia, nitrates and ph are all normal.
