Small tank, 15G and 12"deep. At the moment I have 2 of those e27 LEDs and from what I read looks like its enough. I plan on having 2 clowns and a goby which I will get 1 at a time over a month. The bubble anemone was supposed to be for the clowns then a few easy to keep mushrooms, leather fingers and polyps. Parameters are all good, checked every two days. Ill do water changes of about 15% weekly. Sound ok?
