reef safe fish that school?

Uhmm, that would be 12 for a 70 gallon tank and 20 for a 125 gallon tank. And no that would not be too many for a tank that size. The nice thing about blue-green chromis is they stay small (less than 3 inches in total length). As long as you don't overfeed you will be fine.

A school of firefish are very neat to watch.
Hawaiian Bicolor Anthias also school up nicely, and are very hardy, good eaters.
We happen to have both here at the shop!

You might want to also consider firefish.

I agree...just bought another purple firefish to go with my other & they immediately schooled and stay side by side now. And they are very nice looking fish.

Scissortail gobies. I have a group of five and they spend the day cruising the top area of my tank together. Very cool fish.

Firefish are great for a group that will hang out in the lower half of your tank.

Both are prone to getting into overflows unless you have megaflow overflows which have more closely spaced teeth.

I really like the firefish and if they school well that would be fantastic!
Will different species of firefish get along with each other?
The Hawaiian bicolor is pretty but the get a bit too large.
I do like the sissortail goby and would consider a few of those.
It's good to know that the coral catfish looses those stripes, that's one of their most attractive features and the fact that they school less as they get older is a downer too.
Yeah, I caught the joke about the lionfish on the first go-round Polkster, clever and I do like lionfish but $50 snacks for them . . . prob'ly not . .
Thanks for all the response!
