My blue tang has been acting strange ever since sometime this week, maybe Monday/Tuesday? Has these weird spots on it's head and will dig into the sand on the ground a lot and also rub against the glass and rocks. The color also looks very pale and not as bright blue as it was before. I think it may have ich, but my dad said my other clownfish in the tank too is acting normal, so it can't be ich. The blue tang used to always hide behind rocks and now it doesn't and is always right infront of the tank. A couple of hours ago, I noticed it was laying flat at the top of the tank then would swim back down. It also seems to have a bit of trouble swimming. We're going to test for ammonia, nitrites, and nitrates in the morning also.
I've had this blue tang and clownfish for about more than 5 years now and we just recently moved into a new house about a week ago and put them into a smaller tank for right now because we're still setting up the big tank. My dad also recently bought cleaner shrimp on Wednesday. Any help is appreciated, thanks!!
