Hello. New to this hobby and this is my first reef tank. I have a Nuvo 30L AIO with 2 clown fish so far that I added 2 weeks ago. Upon looking at other Nuvo 30L tanks it seems like I have to much rock/ to high for when I get softies and LPS, as well as a couple for fish. So question, Is this too much rock. I feel like there is not enough room for the fish to swim around and no good places to put coral. If it is too much, would it be bad to maybe rearrange/ take some out with the 2 clowns in it already?
