Yellow tang fin issue

[Lunchbucket]

well i'm not sure if this a problem but my YT has a little bit of a fin issue. it came about since i put them to bed last night (10pm). it's now 4pm. my wife was home sick and she said his fins looked rough earlier (noon-ish). the only reason i am getting freaked out is because i had a YT that got what i think was a bad bacterial infection that looked sort of similar.

here is what his fin looks like. sorry for the out of focus image but it is hard to get a pic of him! it isn't bad but looks sort of similar to what i had happen months ago w/ a different tang

i notice no signs of aggresion from other fish but could be the female clown i guess. this came about over night. i have checked all my water parameters too

am - undetectable
nitrate - undetectable
alk 9.0dKH
ca - 440ppm
po4 - undetectable on salifert (last time i checked 3wks ago w/ a colorimeter it was .04ppm)
pH - 7.9-8.13 swing. lower because the apt is shut up it's cold out

this is what the OTHER TANG looked like the 1-2days before his whole body was covered w/ an ulcer then he died

i soaked some nori in some Kent Marine Zoe and some garlic extract. trying to feed him and boost the immune system. he has been in the system since 10/14/06 and has shown no signs of illness

any help? i can't get him out. anything i add to his food? i can't treat the tank and can't get him out.

thanks

looks like a nipper in the tank, i am guessing the tang is new?

as posted above he is 1.5months old in the tank.

also his gill fins (can't remember the name) look a little cloudy/fraid

Good luck Lunchbucket!

I picked up a similar tang (the dorsal and ventral fins are stubs with similar patchy body) in hopes of getting it all healed up.

mine has gotten better. seems to be healing up. not sure what was up??
