Ah thats good to hear, it did that last night and it still holds the color, it did not turn white.
The bta is a wild caught one, a local reefer bought a lot of them. And has kept them in his tank for a week and they looked good. So picked up one and let it settle in. It just decided to spew out brown stuff after a water change. And how long does it take a wild bta to start accepting food??
