Noddy, my parameters are perfect =] It is a lightly stocked tank, and by lightly stocked, I really mean it. Ammonia-1.5 Just kidding lol, it's at 0, Just wanted to get a good laugh lol) Nitrite-0, and Nitrate is at about 5 ppm. And I'm actually about to do a water change. I've been doing daily 10-25% Water changes, and the temperature is at roughly 82 degrees. Sometimes it drops to 81, but it's always above 80, below 84. I don't know what is causing it. Maybe his slime coat got messed up by being outside of the tank... Well actually that's pretty obvious. But I have a feeling it's one of my other fish. I removed the pleco from this tank just in case it is an infection (Don't worry, the new tank has a lid...Lol) And I'm not going to blame anyone...But I think it's my Exodon's. I have 2 as of right now. We'll see if his fins stop "disappearing" while he's in the other tank. Oh and in case anyone needs to know about my filtration and water changes (Some of which was stated above), I do daily 10-25% water changes to encourage growth, and I have 2 aquaclear 50's, 2 30's, and a 70 that I only run every other day to polish the water off. I also have a sponge filter, and an airstone inside the tank running 24/7. If you guys need any more info, feel free to ask =]
