The weird behaviors might be the temp. I don't know. Does he eat and poop fine?
from what I've seen, he eats and poop just fine. When i open the lid to my kritter keeper tank, he instantly swims to the top corner and where I've been feeding him. I like to drop his pellets everywhere and have him swim and get the food. He loves jumping when I hover frozen bloodworms above him haha. What temp does your heater stay at?
