I have a 58 gallon oceanic with a 20 gallon fuge. I only have 3 small fish, a pair of coral banded shrimp, hermits and snails galor( the ones I bought and tons of tiny babies, red footed conch, purple lobster. Is there a limit to the amount of coral I can add? I have a pulsing zenia, tree zenia, a bunch of mushrooms, some zoos and a toadstool. I am thinking of adding a few more zoos and a sun coral since i have a perfect overhang for it. I just want to make sure I dont over do it. All my corals are small except I do have a large bunch of hairy mushrooms. 340 watts of vho. Water parameters fine so far, I do weekly water changes with ocean water. I know a little riskier but it has worked for my dad for 20 years and seems to work great for me, and since I live on the water much easier and cheapier.
