He has now taken up residence in a powerhead I've been meaning to take out of the tank. I turned the powerhead off sometime ago to replace it with a tunze stream and that's when he claimed it as it's new home.
Yep! It is his official home until I can get aroud to building a bracket to mount my tunze stream on. The mounting brackets they send you are horrible. I ended up just hanging the stream on the overflow because the mounting bracket won't fit over the plastic rim of the aquarium.
