i have a 30 gallon tank w/3 blood parrots. all they do is HIDE. I have had them about 3 weeks now. One of them has started getting black spots. Each day it seems to get a little more or a lil bigger. I have done a watcher change. All water is reading safe or with in safe areas. I just dont know what to try know. Wish I never got these fish, they are so boring.
