Advertisement Showing off the H. swammerdami I have over here. I think I've had these things going for over 10 years now. I almost messed up and hit a dead end. I had to restart with 9 babies left from a bad mishap but it's paid off. I have a good secure number of them going now, I'm not interested in selling right now but I will some day. The containers aren't pretty but work, I have a space problem. It used to bother me, they do this a lot, go completely under water and just sit there but it's never been a problem, I don't worry about it anymore.
