tankmates for a snowflake

[digitalsteve]

looking at adding a fish into my system.. all i have in there is a 15" snowflake moray. i have the usual clean up crew etc. the tank is a 50g.

i want something in the 3" range and it has to be fairly active or my eel will dine. i want to stay away from damsels or dwarf angels . does anyone have any suggestions. the tank is primarily a fowlr. i might be adding some corals over the next month or two , but all will be low maintenece stuff.

thanks for the help in advance
