Red Phantom Tetras

[barry_sheen]

Hi There

I have a 30l tank, with 5 neon tetras and 3 phantom tetras (two male, one female). Everything has been peaceful for 2 or so months. Nothing in the tank has changed but for the last few days the two male Red Phantoms have been constantly barging and lunging at each other. One even goes for the neons occasionly.

Are they likely to hurt each other or is this just some sort of alpha male type behaviour?

Is there anything I should be doing to prevent this?

Many thanks

Barry

Hi,
I'm afraid the tank is too small and you have too small a group of phantoms,
Aggression for dominance is much worse when they are kept in unatural, small numbers. Once it has started, it is unlikely to stop and will usually only get worse
