I just got my first coral, it’s spotted mushroom from live aquaria. I’ve read their instructions on placement and water flow, but I’m wondering, how do I know if these corals are happy/doing well? How do I know if I should move them to a different place in the tank?

Hey! l have had an ORA Wall Pink Hammer Coral for a couple weeks now and I have had it in two locations: on top of rock work with more flow and now I have the hammer on the bottom of tank with low flow. l am new to reefing in general and do not know how to tell if my coral is happy and healthy, since every coral is different. Some of the smaller tentacles on my hammer have small curls in them and l am just concerned. Also, the hammer coral’s tenticles look spread out instead of compact like other hammer’s l have seen. Please give me some feedback. The hammer comes out everyday and never stays retracted, which makes me feel he is just fine! l will be upgrading to a Kessil 160w light eventually. Thanks!! For my tank details: - 20 gallon - Dual Marineland biowheel filter - 500 GPH power head - Clownfish, damsel, chromi fish - Frogspawn and Zoa Coral - Live sand - 2 Marineland LED Lights Tank was established and cycled until levels were at zero before adding anything. Cycling took 21 days before anything was added. l cycled with the product Stability and my water is tested every day. Water temp is kept at 74 with salinity of .022. The tank has been up for almost two months now.
