Hello friendly bros, am in need of help here. Just got a VATF 4" 2nd day only, comm with my 2 4-5"perches and 2 4-5" channa, all look so cute tgt. But previous owner is feeder trained. Am wondering, what kind of feeders can I get? But don't wish to get feeder, instead, how to make it as in FORCE it to be on MP diet cause mouth damn small! I dropped alot of small small bite size MP for him in front of his face but my perch or channa will go snatch. Need some help here, and by the way, does VATF need any air pump to survive? Or it can come up for air?
