Ok Bruce is usually a very active and dark reticulated ray. Yesterday mornin I noticed he was "lookin" funny. He wasnt doing his usual running around. So I fed him and turned off his light. And he did pounce his food.All day yesterday he just didnt "look" right. So I added salt and kept his lights off.
This morning he ate really good but now he is really light colored.
His water is perfect. Ive added salt. Light off (but there is sunlight comming in) and his temp is 86.

So I guess Im wondering is there anything else I should do? Is it possible hes growing? Theres nothing stressing him out that I can find.
Im just worried. Ive read to many threads about how Retic's can just up and keel over. And Im kinda fond of my water puppy! Just want to do everything I can.
I also just to be on the safer side gave him and everyone else in the tank a dose of Metro. Lord knows what they could have picked up. Might as well be as safe as I can be.
