fish compatability question

[hockey nut]

Hi Jim. I currently have two black bar chromis. I like the little guys/girls. I never see them school (maybe because I only have two) . They do love swimming very close to the rock darting in and out. They are a great add to a reef tank imo. They keep to themselves and get along with all my other fish. Including a yellow watchman and his pistol shrimp buddy. A school of them would sure look nice. They are somewhat agressive when I clean my tank. I don't think they like my gloves. lol. ... HTH. Cheers
