My adult bell has always done this.
His favourite hide is a large rock originally used for breeding cichlids.
Hes in there all the time, and he poops in there.
Its gross. Its hard to clean.
Arent they suppost to be clean animals?
Katie, some geckos
can't stand the smell of fish.
Check to see if there is a dead cichlid in there.
Easy to clean poop from any rock...
use 1/4 stick dynimate in an open field.
Light...run like heck.
{Post is a try for humor.}
Take care. HJ
