The clarias ended as Erytrinus-food. Problem was they wanted to use the wolfs cave, thats a no go. He severly chewed on one, and ripped its belly, the second one was rippped in two halfes.
Now he has a lot of Danio for food, and a pair of Trichopodus pectoralis, which he tried to chase the first night, but now he doesnt bother about them anymore.
He is normally only active at night. But I think he gets used to me and yesterday he came out of his cave and was willing to be photographed.
