The last time I was here I was very frustrated and about to give up. Instead I decided to take a step back and take a little break. I was fighting ich, I have lost some fish, but I have learned alot. I now have a 150 g tank with a 30 gallon sump, about 125 lbs. or live rock, the only fish I have in there right now is a huma huma, porc puffer, and one mono argentus. The tank has been up and running for atleast a year and a half, I haven't had any problems with it in a long time. Now to the question. I was wondering if I could possibly add another trigger or maybe some grouper?
