I have had my newest fish in my display tank for almost 2 weeks. My yellow tang lived in a quasi QT
tank for almost 6 weeks and the 3 chromis lived in there for close to 2 months.
I did a 10 gal
water change last night while suctioning out the red slime that is a problem. I added RO
water for the first time with this change as well. The tang has been eating great and has had great color but I noticed today that his belly looked shrunken in and he was struggling a bit. When I got home tonight, he was on the bottom dead with a host of scavengers upon him. I removed him immediately.
Anyway, I am a bit dumbfounded by this loss. I alternate feedings with formula 1 & 2 and marine cusine every other night. I also clip a small slip of green or red algae for the tang. He always ate voraciously and swam alot. Other than his shrunken stomach, he looked great.
My other fish, 3 chromis, 2 damsels and a perc. clown are acting as normal and my star polyps, xenia, mushrooms, etc are doing great too. If this was a water quality issue, would not the corals show signs of this first?
This is the one fish that I really want to have but seem to have trouble with
