Chromis, 1 Or 2?

[smokinjoe2122]

SO I was thinking of adding a blue-green chromis to my tank, as they are typically peaceful, cheap, and I think beautiful, but I was wondering how many I can/should add. My tank already has a false perc. clown, six line wrasse, and watchman goby. Inverts are CC, CC star (leaving soon) and pin cushion urchin. I don't have a skimmer on this tank, just do weekly water changes. How many can I add before I get dangerously close to my max bioload, or am I there already? I just use like 40+ lbs of live rock and hang on filter with chemi-pure and carbon pads.

Thanks,

Joe

Chromis shouldnt really be kept in pairs or singles. The stronger of the two would probably pick the smaller one off. They do best in larger groups so agression is soread out more.
