Can anyone give me advise on whether I can introduce successfully a 3 inch Green Phantom to a 180 litre tank that currently has four 2.5 inch Clown Loaches in? I ask as Clown Loaches are very gregarious especially at feeding and Phantoms seem to be the opposite so I don't see how the Phantom can compete for food. Any ideas? May be I need a bigger Phantom, may be that doesn't make any difference, I don't know?
