Alright.... you have to look at each tank differently. Depending on the filtration, you could have alot or a little fish....
My list for my 75 is:
1X Green Target Mandarin
2X Lg Yellow tangs
2X 10" engineer gobies
1X foxface
1X cleaner wrasse
4X green chromis
1x bi-color angel
I think that's all. I have so much rock and sand that I don't run my skimmer during the day. I just recently changed my light schedule to 12 hour MH!
