Where to put a hammer or a torch
Leave more room than the skeleton suggests. Much more.
Euphyllia extend sweeper tentacles at night that reach far past the visible flesh — fifteen centimetres is ordinary for a torch. Whatever is inside that radius loses.
They also do not get along with each other across species as reliably as the hobby claims. Hammers and torches together is usually fine; either one against a frogspawn is a coin toss.
Medium flow, medium light, and somewhere you can see them: an animal that opens beautifully in a corner nobody looks at is a waste of a good coral.
