is there any thing else i need to know about this coral?
They won't much appreciate the high water flow
Euphyllia sp prefer a med to low waterflow, just enough to lift and sway their polyps.
is there any thing i have to feed it or put in the water?
Simply feed the fish in the tank and the frogspawn will eat too. As for the water, IME
, Euphyllia are sensitive to ALK
levles, so you'll want to stay on top o those and your CA
, otherwise they receive everything they need from food and regular water changes.
