Scolys not doing well

[WhatTheReef]

What do I do to get these guys healthy again? Any tricks and tips you guys use for care for these?

The white one you can see is receding now and the bleeding apply I bought messed up, started doing better and then stopped. all other brains, wellso's, and scolys in the tank couldnt be doing any better...

Here's another one in my tank that is doing fine just so you can see its no other corals in my tank besides those two above.

What's your water parameters like? They like low light and low flow. They may not do well under MH unless it's shaded
