Alright, so I used to have a very nice 29gallon FwLRO tank, but I shut it down in order to help my dad out with his 72 reef (which is going great right now I must say -pics to follow). Since working on my dad's tank I've begun to miss my nano tank, so I've decided to set up a 5gallon nano in my room. My question is however, would stocking the tank with 3 snails, 1 clownfish and possibly a small goby (something like a watchman goby) be too much in the tank?
