Part of your description is similar to our recent experience with green chromis from LFS over the past 3 days in the QT tank. We started with 6 (their limit, and all we wanted anyway). They mostly hung out toward the bottom of the tank, but otherwise nothing seemed out of the ordinary. This was our first fish purchase from this particular LFS.I'm not sure if this is classified as a suck fish or not. I had gotten some Caribbean blue chromises. Beautiful blue fish. It was a group of 6 from Divers Den. Two jumped out initially, so I had 4. About a year in. 3 of them picked on one. Until he had to find a hiding spot and would no longer eat. Then there were 3. . . Then all of a sudden the 2 remaining just started attacking the third just out of the blue and they were vicious. I'd never seen them act like that. The third had some damage to his scales, started swimming eratically and stopped eating. Had to retrieve him before he got sicker and spread something. Then there were 2... A few months later one of the two started acting erratically. Looked to have swim bladder issues but upon observation he had damage to his scales, and further observation the one remaining was picking at him constantly. He too died, and there was one.. Which I still have. This picking off of chromises happened over a 2 year period. The one remaining is moving into his 3 rd year in my tank.
Doing some research I have discovered Chromises in general have a 2-3 year life span in captivity. Did the fish know they were dying due to old age and decide to help the process along? Or was there immune system weakened due to old age and their health declined, this brought on further attacks out of self preservation?
The other fish in my display are going on 3 years old with no signs of disease or illness other than maybe obesity. . .
The one chromis remains peaceful now with his other inhabitants. So, I have no idea if it was disease or fish are just malicious and just snap.
i had a pair of Anthias i just looked at the tank it was dead laying on top of fan i always notice when the fish start coming up for air a little and try to hide i know something is wrong but they always go to the top of the tank can't figure it out first fish in a while hope it stays like thatPart of your description is similar to our recent experience with green chromis from LFS over the past 3 days in the QT tank.

We are down to 2 today. I thought those two were gone this evening at feeding time, I found them hunkered below the end of the heater. Temperature checks out what the probe is also reading, 79°F, water parameters same as other tanks using same saltwater. After they ate, one hung out under a corner of rock and the other stayed tucked below the heater.
They are pretty transparent, it takes me some time to find them especially without the light. So far no signs of attack or illness, so I don’t really know if they are sick, but 4 of them died. The only other fish sickness and death we’ve had was a shipped fairy wrasse, where this forum was helpful to know how common that problem had become.
ok have a good question i sent my ICP kit away to Colorado about 3 and a half weeks ago how long is average time for a answer i'm sitting here like a expected father just want to have a idea thanks Garyi had a pair of Anthias i just looked at the tank it was dead laying on top of fan i always notice when the fish start coming up for air a little and try to hide i know something is wrong but they always go to the top of the tank can't figure it out first fish in a while hope it stays like that
Oh, the research I miss before picking up a fish… evidently there can be only one chromi. Last Chromi Standing.

So, it’s a different kind of “sick”.Oh, the research I miss before picking up a fish… evidently there can be only one chromi. Last Chromi Standing. Noted.
