My 2.5 gallon reef tanks is still chugging along at about three weeks. Used 3lbs of really well cured live rock, brought it home in a bucket of saltwater, and apperently skipped the cycle completely. I have started to add what i call "freebee frags" from work (polyps and zoos that have grown onto shells or fragged off larger pieces). I don't want to have to dump alot of nutrients into such a small tank in order to feed them (there are only three). I was wondering what size prey items most polyps eat? I keep a constant supply of live microworms and bbs for my freshwater tanks, and was wondering if either would be of any benefit in a reef setup? How would I feed them? Target feeding with filter on/off? Just drop them in?
