Well, I guess well just see where this tank goes. As noted before. My set up 20 years ago was under ground, with no problems. The tank has cycled, and levels have been good since then. I do reg water changes.
As for the Tang. During last nights minor warter change. We seperated him from the tank, and shipped him up to my sons house for a bit of time. The tank seems calmer already. And, the bi-color angle is out much more. Thinking just a day, or two. Then, re-install him.
One more thing. I have life growing in my tank
help I.D. please
