Is anyone familiar with these?I picked two up the other day. I was going to buy some Khulis, but it would have had to be a special order. Seems no one wants to stock them since they're never seen to be bought. When looking for alternatives the Zodiacs were suggested. I let them know that I was looking for something small for snail control. They assured me that these will not get much bigger then 3-4" and will eat snails. I've been watching them, but I haven't seen them eat anything yet. No snails, no flakes, no freeze dried blood worms.
