well, you need a tile saw because you don't want to damage it. And if you put it in a hamster ball type container, it will grow much faster in my experience. My friend has quite a few color morphs of rats, all of which he has fragged multiple times.
i have no idea how this thread is still here but you guys are so funny, jw how did we go from overfilled tank of puffers to fragging animals? lol sounds kinda like a big jump to me but all in all its funny
