I have a couple of sps corals that have new growth on the top, but the bottom seems to be slowly receding on one side only. I think it is because of the led lights, but I would like some other opinions. Is there anything I can do?
More than likely shading from the LED's. I have this happening on a few mini colonies and they've been this way for some time, bu they all continue to grow. I'll see if I can grab a few pictures for reference to see if it's the same thing your experiencing.
Check for bugs too, if you see white spots it's more than likely bite marks from AEFW. Look on dead tissue for eggs, tiny little orange dots. Just a thought
