It was freaky. I have a small breeding box that I keep my small endlers until they are big enough to live outside it. Its slats in the bottom are big enough so they can fit through, so I stretched pantyhose to prevent their escape. Then today, BANG! Three of the 12 or so were outside the box. I saw that the pantyhose had slipped off a corner of the box. I quickly pulled it back over the corner, and caught two of the escaped endlers. The third one I tried to catch, but then, POOF! He disappeared. So I've lost 2 endlers, one was an experiment to see if they were big enough to put in the big tank, but he... didn't survive long. Found him stuck to the filter intake, dead as a doornail.
