Green BTA Turned Brown On Edges

[Joe.S]

Hi all,

I got a green bubble tip nem back in June of this year. The first few days I had it it looked amazing, bright lime green with nice bubbles. But as time went on it lost the bubbles and turned brown on the rim of it, as well as got duller of a green, however its over double the size I got it as, but maybe that's just it fully open. I've been told its the zooxanthellae returning and that's a good sign, but again its been over 2 months now. I run 2 AI Hydra 32HD over my system. Any ideas? Thanks and happy reefing.
