Of equal importance, can you test your water for:
salinity [refractometer: 1.025]
ph [ph meter] 7.9-8.3
alkalinity [I use Salifert] 8.3-9.3
calcium [Salifert] 400-420
temp stable around 80
nitrates low; ammonia 0.
chaotic flow [a Sea Swirl is ideal] Not necessary, but helps growth.
Start with one, or with a candycane, which divides fast when happy.
2 of the 3 euphyllias [hammer, frog] can touch with no problem. Torch is touchier, though mine, a thin-tentacled torch, touches frog quite happily.
Keep them clear of the sweepers of: bubble, galaxia, brain.
Avoid having: mushrooms near them, or in the same tank, actually. They get into wars. I recommend against keeping softies with these corals, for the good health of both.
