Any color change on a nitrite test reading is not a good sign. The NO2 should be undetectable in a properly cycled tank. With a still newer set up there are "ups & downs" especially when adding new waste producing animals. It can take a little time for this to settle down. Keep in mind that bacteria grows to meet the demands placed on the tank so with each new addition of a waste producing animal, time must be given for the biofilter to catch up. Personally I don't think 10 gal weekly water changes on a 75 gal tank with 5 damsels as the ammonia starter will have impeded the cycle to any real degree. In future though, please read here...( not a lecture, just a point of reference )ph34r3d said:The nitrites I am seeing may even be none.. it's just the reading of the test.. it's not 100% clear.. ya know??

Water changes are definately in order. Please be sure the new SW is well aged/aerated for a day before use. Do several over the next few days, 10-15 gal each.
How long have you had the angel and how are the damsels behavior generally towards it? Agrressive or passive?
I would also like to know, this can be especially important dendant on where the LFS keeps the chemistry/parameters of their tanks.BillyZ said:Also, tell us how you acclimated these new fish to the tank.
Given the decsription of the fish's behavior ("he is swimming weird.. and kinda floating") and no mention of skin abnormalities I am inclined to think an internal ailment, possible internal damage from netting or acclimation. There is also the possibility of cyanide capture.
If you've had the angel for any length of time I might also suspect diet...
