I’m planning on picking up a IM 50 gallon AIO lagoon in the near future and I wanted to small to medium fish so the tank looks bigger. Preferably smaller fish but I definitely plan to get a pair of clown fish and the rest I’m open to suggestion. I do plan on having mixed corals as well but I’ll make sure to have caves and open spaces between the rocks for the fishes to swim. Looking forward to hearing your suggestion!
