Fish Suggestions....

[Minkota]

I have a 150G (48 X 24 X 31 Tall) Mixed Reef. I currently have 4 Green Chromis, 2 ocellaris clownfish (one is becoming aggressive), Watchman Goby, Purple Firefish, and regular Red Firefish. As mentioned I have an ocellaris clownfish that is becoming aggressive and has started biting me when I put my hand in the tank so I figure id better make any other additions to the tank sooner rather than later. I am trying to make it a very peaceful tank; I do not have any Tangs at the moment and do plan to get one I am just not sure which one I want yet. I would get some opinions what else I should consider, that are Reef Safe, Colorful and Peaceful.

There are plenty of wrasse and anthias out there if you don't mind having a cover on the tank and feeding 3-5 times a day

^ Yep, plus assessors, dartfish, royal gramma, basslets, blennies of the Genus Ecsenius.

Decide on 2 tangs for your tank.
flame angels pair or trios
Marine beta pair
Watanabe angel pair
5 or 6 Roula gramma
Madarin dragonet pair
Orchid dottyback pair
If you have a sand bed then Leopard Wrasse

Regal angel

Ditto on some angels - I love my flame angel and have always liked lemon peels. I've heard that if you add them together you can minimize aggression.

Every tank needs some wrasses too. There are some really pretty fairy and flasher wrasses out there. I have an orange-back fairy, a McCosker's flasher and a Carpenter's flasher that all get along great with everyone. Leopard wrasses are awesome, as are mystery wrasses, but they get mean as they get bigger. Halichoeres wrasses are my favorite, but they eat shrimp.

Midas blennies are a fun, cool fish as well. Yellow-candy hogfish is another active, peaceful fish.

Good choice on the tang. With a 150g, a purple tang would be a great choice, or a yellow. I like my blue tang as well. You could probably fit a Red Sea sailfin tang, those are awesome as well. Chevrons and Powder Blues are beautiful fish as well. Although pretty much every tang is "semi-aggressive." If you are just getting one, I'd recommend a purple or Chevron.

Liutenant Tang or Orange Shoulder, Both beautiful fish, Both do great in a community tank, Both will get big but not for awhile.

I love my Yellow, Purple, Powder blue and Chevron tangs. I also loved my Yellow eye Kole tang that got eaten by my carpet.
