Thanks for asking.
Beautifully.
I started it on Hikari carnivore pellets and soon moved it to Massivore. Eating anywhere between 2-5 Massivore each night and has packed on width and length.
Matter of fact, I've been thinking about either moving it into my 75 gal and, around Christmas, transfer it into the 220 with the pikes I'm growing out. But I may simply move it into the 220 right away. Only thing is that the 220 only has a large dat and a large pike right now. I don't want the knife to get picked on by a curious, bored dat.
That dat is so bored, it has started to take my plants apart, leaf by leaf.
