Help with Corals

[ziggery]

I recently got into the hobby cycled the tank and everything and decided to pick up a hammer coral frag. I can't seem to figure out why it won't open up like how it was at my LFS. For reference i have another torch which seems to be doing better than the hammer is unless I am mistaken. Should I be worried about it dying or should I let it stay put

water conditions seems to be fine


salinity 1.025/33 ppt (ppt slightly low)

mag around 1475-1500

calcium around 450

Alk around 8.6-8.9

pH 7.8

Would appreciate any help or feedback Thanks!

How old is tank???

Hammers and torches (and frogspawn) are NOT good beginner/starter corals.

If parameters are stable the next thing would be light and flow.
