Fighting Wounds or something else?

[Slick Fork]

Hi there,

In the beginning of January I bought 10 Chromis, They've been in a 33 gallon quarantine tank since then. I gave them a few days to relax and then dropped the salinity to 1.009. 1 died before I even dropped the salinity, and another jumped. After 4 weeks of hypo, I've brought the salinity back up over the last 7 days and the survivors are theoretically now ready to go into the main (100gallon) tank.

Now, most of the remaining 8 have reddish blotches of one degree or another (have had for some time) and they seem to be getting worse. To me and my wife these look like fighting wounds as scales appear to be missing and it looks like a scab you get when you skin a knuckle or something. They are all alert, have tremendous appetites and look otherwise happy. I have noticed when they are not eating they spend half their time brawling and chasing each other around. The one who has the most spots seems to be the most picked on.

Water parameters are all where they should be and the tank has been getting at least 1 9 litre water change daily for the last little bit as I bring the salinity back up.

My dilema of course is what do I do? If this is a fungus or something that survived hyposalinity I do NOT want to put them into the main display. However, if these are fighting wounds then moving them from the 33 to the 100 tonight like the plan was will be the best thing for them as they will have room and rockwork to hide and race around.

Any thoughts???
