What size tank

I really want a 90+ gallon,it will most likely be a semi-reef environment. I will probably put hero in there and some 1-2 other personality fish, then i will have some schooling fish, a few gobies, wrasse, and clowns or other decorator fish, recommendations anyone.

You could get a second puffer, maybe a solandri or something?
Chromis' are great school fish, beautiful and hardy. Make sure you get a small reef safe wrasse, others get very very aggressive.
Maybe you'd like a butterfly fish or yellow tang? Their both fun.

Well it would be another puffer since today i had a very unfortunate accident. A snail in my tank died(a big one) and i came home from school and everything in my tank had died, my sweet little puffer and my damselfish nd the day before i have reason to believe a non'reef safe crab got my royal gramma. The inly thing sopping me from tearing my tank down is my two corals.

Wow that stinks I'm sorry.

Yeah i am really bummed out. For now my fish expeirence has come to an end though i am still very into them. I hope to get back into them though, maybe when i move.
