Hello. I have a 20g reef tank and ultimately I want it to be set for success. I kinda wanna incorporate a star fish and maybe taking out the snails? Or a diamond watch goby to help the sand bed? As of the moment I have 4 snails and two hermits for my clean up crew. I also have 3 fish. A black clown, a damsel, and a pigmy Angel. If you have any questions or want to see more, watch a few update videos I posted on my YouTube.
