potters agelfish help

[Go29]

HI everyone i am searching reefcenteral right now for possible causes or cures so i really dont have the time to test my tank... i have clams sps anemones the rref tank works so i can tell you my water parms are fine... anyway while i was out today my rents decided to surprise me for christmas early and picked up a potters angel from the lfs ... long story short while they acclimated him they didnt shut my lights off ( sunlight suppkly t-5) so i think the bag he was in got over heated. they said he looked fine, but after 20 min of acclimation he sank to the bottom of the bag and began to breathe hard, now hes liing on the sand in my tank... the area around his anus ( if thats the right word) looks like a red dot is there so i didnt know if it was an ulcer or somthing similar.... basically what are your thoughts as to what couldve happened or what are some possible treatments..... like i said he is breathing very hard just laying motionless on the ground... i added a air pump, and stress coat to the tank, i do have formalin and marcyn on hand but didnt want to scoop him out and put him in a quartine right now as just in case its all stess and mabey hell calm down.,..,, please help thanx for your time
