So, far Fred is swimming and eating as usual. I felt so bad when he jumped and we didn't know whether to pick him up or scoop him up. Luckilly he jumped back into the net. There was a funny whitish color after we put him into the tank. The color eventually changed back to the regular maroon. But this morning he had a yellowish piece of I don't know what hanging out of the 2 front fins. I didn't know if he was hurt or relieving himself. But after about 15 minutes I think he rubbed on the rocks and it fell off. It is not there now. Let me know if there are any things that I can do.
