i am planing to get an aggressive tank along side my reef tank and need help (or decide) what fish to get in it.
its a 55g and iwould like some photos of your aggressive fish
certain species of eels and dwarf lions are all you should be looking at for a 55.
triggers and porc puffers need too much room for that tank, and unfortunately a lot of eels require more room as well.
look into a wolf eel or a jeweled moray
