I got my from Matt "Al G blenny". I didn't feed it until last week. After feeding it for several days it split 8) . I'm now have two adults. Make sure you feed them. They grow much faster if you feed.
I got 2 from the club group buy a year or so ago. I don't target feed them, but they manage to catch scraps from time to time. Now I've got around 10 scattered all over.
I think it was JoeMack who organized the group buy. Where the heck is he?
I'm sure they will split even you don't feed them. But if you want to have a lot quick... Feed and Feed .. ... I will try to feed them at least 3-4 time a week and we will see what happen after a month...
