Hey, After much research and helpful hints on this board, I have begun my octo setup. I Have a 55 gal tank, protein skimmer, 50 lbs live rock and live sand. I also have a DIY wet/dry filter. I used a 20 gal tank as the sump and built my own bio-tower (includes carbon filtration) from acrylic. (still a little woozy from the fumes) Anywho, I was wondering what the best method of cycling the tank would be. I don't want to use damsels b/c I read a post here which said that they would harrass the octo. Any suggestions as to which fish might be best or should I just "feed the tank" ? Also, can one put two Bimacs in a 55 gal tank or will they fight? Thanks in advance!!!!
