I have a 225 gal FO
tank and added fish last month. Since everyone is still alive and my levels are consistently good, I want to start adding more fish. Right now I have 2 Damselfish (3-spot Domino and Blue), 1 Blue Tang (Dori), and 1 HI (yellow) Tang. I have 120 lbs of base rock that is starting to show some green and red algae growth. I have a "cleaner pack" (snails, crabs, worms, sea stars, and shrimp) so I'm not too concerned there, I just don't want them eaten by their tankmates.
I'm very concerned about tank compatibility more than anything and want to make sure everyone will get along. Of course since I have Dori, my niece wants Nemo (clownfish) too (actually she wants Nemo I and Nemo II, lol). According to the charts I should be OK there.
I guess what I want to know is how many more fish can I buy with my tank size and what would you recommend with this temperament? I keep reading the compatibility charts, but I get confused. Also, I will be adding live rock, but I don't plan on having a true reef aquarium. If you can also suggest some low light coral or mushrooms that will look good that would be appreciated.
