Are Channa lucius communal? Or at least, not overly aggressive towards their own kind? I have a 5" one in a 3ft tank, and I'm wondering if I can keep them as a group - a local LFS has more in stock (and going fast!). Also, how big do they get? I've heard 25cm, but I don't really trust that source. Sorry for buying on impulse without doing research beforehand; I just couldn't resist taking home at least one that day.
Thanks in advance.
EDIT: After looking at some members' pics I think mine could be C. maculata. Mine consistently changes colour. Is this a trait of C. lucius? I'll try to get pics but this fish hides all the time. However, its head is rather pointed, like a pike. And if I'm not wrong, "lucius" is Greek/Latin/whatever for "pike" or something...? I have no idea, really.
