Help! I got a new 45 litre tank 5 weeks ago, cycled it, and put 6 neon tetras in a few weeks later as the water was fine. A week later I tested the water and it was good so put in 3 peppered corys. A week after they've gone in and one has lost its barbels and is breathing really heavily. The other two are fine and happily swimming around.
What do I do?
