i was originally going to get this 55 gallon long tank for freshwater, but had a change in mind. i had had a 30 gallon reef tank once before, and loved it but had to get rid of it due to no space/money. fortunately i'm going to start up again, but this time take more of a fish only route. i'm going to aim for clownfish. i know they're terriotorial and all [like most saltwater fish] but how many could i get in a fully established tank? i've never really had inverts in a tank either, and i'm curious to add some once the tank is established. could you recommend any easy inverts?
