Keep your Yellow, Hippo and your foxface... you might be ok with those.
Other than that, I'd only have little fish (gramma, wrasse, cardinals, gobies, jawfish etc)
How do you like the foxface? I was thinking of one of those once.
Also, if you bought all those fish for your 90 from the same LFS you might want to shop elsewhere. They shop obviously isn't in it to help you, just there for the money.
My LFS will do just about anything for the fish... even take them back and quarrantine them if they get sick. You're still out the cash, but he'll try and nurse them back to health.
