I have a relatively small tank-46 gals- 57lbs of lr and 50lbs of live sand- starting with a couple of ocellarus clowns and waiting to get a diamond goby- I'd like to add a few blue yellow fin damels but have heard bad things about damsels - i've read that these are the least agressive of the damsels- any comments ? I'll be adding a 6 line wrasse, and a mandarine dragonette down the road-I'm wanting a peacful group...would the damsels be a mistake in a community tank?
