Well, my Haitain Purple tip committed suicide two days ago, he had wondered up to the top of the tank, in the back and the next thing I know, he was gone. He had done it once before, but I found him three days later under a large rock towards the middle of my tank that acts as an overhang where my cardinal fish like to hang out.
Anyways, this time, he committed suicide, I found him at the bottom of my overflow box under my bioballs, how he got in there I have no idea. I didn't think he could slip through the little slits in my overflow.
He was doing fine before this. I will have to venture out to the LFS to get another one. My perc clowns miss him.
