indian butterflyfish HELP

[ttl]

how big, how hard, and what do they eat. And would they be fine in a red sea Max 250 (65G) with...
3 green cromis
1 true percula clown
1 firefish
2-3 longfin or schooling bannerfish
2 sleeper goby
1 Leopard wrasse
2 royal grammas

 

[small triggers]

no.... you are wayyyy maxed out on fish....
the bannerfish are gonna get big and there would be no way to try and shoehorn in the butterfly, if you already have all these fish id say call it good... if not you could nix the 3 chromis', 1 sleeper goby and the wrasse if you wanted to chance it...it would still be tight

i already have the cromis, clown and firefish, and i really want the wrasse not necessarily the gramma and gobys. but i really want the butterfly and bannerfish-2
