Upgrading to a 150g tank soon, I'll have about 400# of live rock. I've never really been a big fish person. I really like my aquarium for the coral, but my family and friends really appreciate the fish more than anything. Now that I have a bigger tank, I feel I should exploit the newfound space.\n \nWhat do people generally fill their tanks with fish wise? It's a 5' long tank, aquascaping is to be decided still....\n \nMy only required fish is a yellow watchman goby. I'll be bringing over a clown, bicolor dottyback, and a coral beauty(all of which I'm OK taking back and trading in for credit at my LFS if there is something worth getting over these guys.\n \nThank you all.
