Rescuing a yellow tang.

[AdamsB]

This little dude is doing pretty good. Still a little timid and has slowed down eating compared to the first few weeks but still finishes his food. Dorsal fin is healing nicely but his head and dorsal are a little faded. He's got probably at least another month before hitting the display tank. I may even try to remove my 6 line before that, he can be a real wrasse hole!

Any advice on treatment for this guy much appreciated. All parameters are good, salinity around .025 temperature 25c, 20G long, tetra whisper internal filter rated for 40G, korella 550, 12 or so lbs of live rock, aerated while lights are on (timed for 9 hours a day) single t5 10k bulb, glass cover, painted back, 1 side and bottom.
