So here's my 12 Gallon Fluval Edge tank, has 2 damsels in it and 3 hermit crabs and 2 snails for some clean up. I'm looking into getting rid of the damsels because they are aggressive and are not good with other fish. I also want to get some corals possibly add more LR. Any suggestions on what to add for more decor and fish ? Trying to set up a nice reef tank with some nice corals and two to three fish
