Never seen it much, apart from when cleaning.
It's taken up residence at the back of a sponge filter even though there is caves in the tank for it.
Recently i've noticed half an hour or so before the lights go out, it pokes its head down from under the sponge filter, watching the other fish, then it slowly ventures out from behind the sponge, sometimes onto the tank floor.
Managed to get some pictures of having a peek out, before it slowly works it way to the tank floor, though as soon as it spots me its back behind the sponge again !
