I have had my fish in the hospital tank for the last five and a half weeks. They will be going back into the DT this weekend and I have noticed my green chromis acting a little weird and almost hiding and not eating. I seen today after work that one fish was missing his tail. So after eating and doing research I went back to check on him and noticed that my little black mouth chromis is picking on the green chromis. Unfortunately the one has died due to injury but the other is still doing ok.. My question is will this stop after getting into the 210g DT or should I be possibly finding a new home for the little guy?

I assume they lived in DT together before. How were they then? How big is the hospital tank? Either way, I’d hold the aggressive one back a week longer than the injured one to let injured one get comfortable 1st and heal a little.

idk how the breakdown works, but i believe that Neoglyphidodon group are normally in the damsel crew and are pretty mean ones at that. the neon velvet damsel is in that group, i'd find a new home for that feller

Quote from live Aquaria:
As the fish matures, it becomes extremely aggressive towards other fish causing problems in selection of other fish to add to the aquarium.
I’d say find him a new home.

Seems like they’re just having issues related to territory. If there’s an issue, you’re gonna have a heck of a time pulling 1 out of a DT that big. But if they were find before, id give it a try again. If injured guy’s missing its tail, its gotta be slow. Maybe u can catch it and keep it in an acclimation box for a few days so it doesn’t keep getting bullied?
Edit. After reading Hemmdog’s post, I’d rehome the aggressive one. Or maybe keep it in a nice display refugium? If u don’t have one, now u have a great reason to get one. Upgrade time

This is an EXTREMELY AGGRESSIVE fish. Do not put it in the DT.
Good catch. Nasty genus.
He has already taken out one green chromis and started on the other. The fire fish and royal grandma have stayed hidden too. I have since put him in jail ( a screen breeder ). they are coming out off copper tomorrow and then into the DT. Ill probably throw him in the sump. My question is will the opposite light schedule effect him until I find him a new home?

The opposite light schedule isn't an issue. Most fish are from an opposite light cycle from where they come from when put in our tanks anyway.

Most fish kept in our tanks come from the Indo-Pacific, which is on the opposite side of the globe of North America.. Where they were living when they were captured, it would have been day there while night here and vice versa. And the fish do just fine when transported to the opposite light schedule.
