if you over feed your fish and the shrimp eat that then they wont want to eat any aiptasia in the tank. which the aiptasia would also reproduce faster if you over feed.
dunno if anyone said this already or not but you should try and put your overflow box in the center of the tank. unless you want it on the side, youll need to move that jet away from it tho.
I'm looking for live rock, sand stars, shrimp, snails, hermit crabs and any kind of macro-algae. please pm me if you have anything i would need.
thanks
