List of fish, which will work

[Synergy]

12 GAL JBJ nano

True perc clowns (1 or a pair)
Bi-color pseudo
Red firefish
Yellow watchman goby

Which combination of those fish would be the best? Any other nice small fish that would work better. Looking forward to hearing all the suggestions!

I would do one perc, the firefish, and the watchman goby. Should be a nice combo and keep a 12G looking active.

Go big with a Helfrichi Firefish awesome fish and since youre not stocking too many fish, it could be a cool showpiece piece...IMO

I'd to 2 fish max and maybe a shrimp, IMO

I'm with Mike. Two fish max. The perc clown will get to be about 3-3 1/2" when fully grown. My single female perc clown owns my 30g cube.

Skip the pseudochromis. They are known for their aggressive nature.

I am always partial to a pair of clowns.

If you can keep ontop of your bioload, water changes etc.. I don't see why you could'nt include a watchman too (even with a pistol shrimp). Gobies almost never go far from their home, the sand, so they should'nt bother eachother. Again this is if you keep up on your maintenance.
