What size tank would I need for this stocking list?

[jayjay5531]

Currently I have 5 blue-green chromises in a 36 gallon FOWLR that I inherited from a friend (so far no problems with fighting, if there is though I can give some to my LFS). I want to get a bigger tank and have the following. How big of a tank would I need for this, bio-load wise?

5 blue-green chromises
1 midas blenny
2 clownfish
1 flame angelfish
2 green clown gobies
2 firefish (pair)
1 orchid dottyback
1 royal gramma basslet

Thanks so much!

The chromis will eventually fight and only one will remain. As for the other fish a 90 or larger would work.

Hey JayJay - bigger is always better if you can swing it. A standard 120 gallon has almost the same footprint as a 90 (just about 6 inches more front to back), with very similar lighting requirements i.e. no significant jump in coverage needs - whatever would work on a 90 would likely also work on a 120. Plus, the extra depth give more dimension and aquascaping options. It wouldn't take you any more money to set up the 120 over the 90, except for a marginal increased tank cost - which is nothing over the course of your tank. If you plan to get any tangs in the future, you'd need to start with at least a 6 foot tank.

The dotty back and the gramma may give you issues
