Eh, I buy massivore already for the Bichirs and large catfish I have. I keep so its not like 1 pellet is much, and from my experiance, it makes fish grow faster due to the better nutrition it has compared to most other pellets, plus almost every fish I fed it to loves it. I wanna have the little guy grow quickly so he doesn't have to be in the box for too long. He tries to swim through the plastic netting, I would assume it causes him stress. I wanted to ask that if you think putting in Molly fry into the box would work, as in the Lungfish not hunting them down. The fry are bigger than its mouth so I would assume that he can't eat them?
