So I finally got my mean damsel out of my reef tank, and thru him to the lions! Literally. So I'm sitting here looking at my tank and talking to the woman about what we should get to take his place, I'm not sure how many fish I should have in a 90g reef because there is the great debate on 1fish per 10g or is 1 fish per 4g... Depends on who you ask, in my opinion. My current live stock includes: kole tang,scopus tang, 2 clowns, 2 shrimp,sand sifting star. Went my Lfs today, and seen a pouder blue tang, it was beautiful, but idk in a 90g with the fish I have in there now.
