Hello,
I have two ancistrus (dotted and albino) and
I haven't seen my albino ancistrus for days now, even though I spend at least 2 hours a day starring at the aquarium.
Where could he be? This is my setup:
Could he be somewhere inside the cracks of the piece of wood I have?
P.S. Once, when I was re-decorating my tank I lifted the wood and he was beneath it even though the wood is held by gravel.
