Congo Tetras Getting More Aggressive

[deanrar]

I had 5 congo tetras and lost 2 over xmas when my housemate was "looking after the tank" for a few weeks and they seemed fine until about a week ago. They have always played chasing games but now its getting increasingly violent and as i only have males would it calm them down if i maybe swapped 2 of them for females or would the remaining male still keep attacking the females as aggressively (have never seen any females in local fish shops so will be tricky).

The best thing to do would be to make sure you have 6 or more congo's. As they are shoaling fish they need to be in larger groups and at the same time this would reduce the agressiveness towards 1 or 2 of them, as it divides the load among a larger number of fish.

Good luck!
