I have one. Just got it. It is the Acrochdidus granulatus though. I wanted javicus which I hear are more of a hardy Acrochorididae. I have not wittnessed him eat yet. However i am keeping him like the seller said. Aged water, tank is half full with plenty of wood and fake plants to anchor himself. I also have a little sand on the bottom. thinking of adding more for him to borrow down.
