Ok, I know I am definately the rookie here. I have read so many different threads and info that it is making my head spin. So here is what I have so far: 60gal long, some live sand mixed with regular and shells, some rocks(not live), decorations, and some hiding places. In all the articles I have read it looks like a Bimac would be my best bet(not as much nocturnal and interactive). I have had my tank set up for about a week now so I still have almost 3 months till I can even aquire the octo. I have had 10 damsels(2 dominoes-seem to be passive, 3 green schoolers, and 5 blues, way too aggressive) that the LFS said would be good to cycle the tank. I am just finishing my Alk spike and all the other readings are looking good(salinity 1.026, ph 8.0, nitrate 10ppm), the temp is a little warm at 74 deg. I am using an undergravel filter, fluval 450, and a jebo reef style protein skimmer 180 with power head. Any and all info and suggestions would be greatly appreciated as well as suggestions for compatible fish. ps. Thanks to Animal Mother and Monty for your help so far on the other thread!!
