Okay so i figured they need time to adjust but here we are almost 4 month laster and they barley open and none gave grown bigger or spread
I have since just glued them as i got annoyed and assume not being moved will help
But now 2 months glued and still no growth
I feed them like all my corals
The others next to them have grown fine idk what is there deal.
I do have some aiptasia i guess grew back after i hit them with the X but yea ignore them they are being delt with lol
