My 400's have now been running 4 months, i am very pleased to say the least. My acro's have gone nuts, the growth is very good and colouration has improved dramatically. I'll post some more pics soon.
I've only added one new fish which is a mimic tang(lemon peel) which the yellow tangs beat terribly, but he's now settled in and they have finally excepted him. My moorish idol , i'm going to get rid of as he's gone very large, and i will get another juv. I'm also going to catch my sailfin tang, he's gone huge and really looks out of place compared with the others.
