Ive have my Blue tang for maybe a week now and immediately she looked great in the new home(she's about 2 1/2"). At the LFS guy told me they are very shy and wont come out for few weeks after being added to a new tank. She went in an immediately made best friends with my Coral beauty. Two of them would swim all over the tank together in and out of my rocks etc. Also she was eating very healthy right away. After about 5-6 days I stopped seeing her come out at all, for about 2 days she hid completely behind my rocks and I started to think there was a prob. I finally saw her lastnight stuck to my power head, it appears she was coming to the surface to gasp for air and got stuck up high on my power head. This was a good thing because I was able to immediately net her and get her in my quarantine tank. She looked as though she had Ick and or another disease, very discolored and sick looking in only a day or two! Ive got her in alone with Furan 2 (which always works wonders) and she has survived 24 hours now in quarantine, but is still not looking good. She can barley swim and tries to make attempts to get to the surface for air. I do have a large air stone I added as soon as she went in knowing she wasnt getting much oxygen. Also, water parameters are perfect as always thanks to my scrubber .023 Salt 0 Ammonia 0 nitrite 0 nitrate 0 phosphate 8.2 PH 79 degrees Apparently Ive been reading its VERY common for new Blue Tangs to get sick easily, does anyone have advise what I can do to her get get better faster?
