BuggerWell, the fry thing didn't work out anyway. I couldn't get any fry quickly enough and I was having a very difficult time getting a snail source. Despite my best efforts to get them to eat prepared foods and meaty frozen fare, they refused to eat and I lost both of them to starvation. I ended up rehoming 5 of the 7 platies and now only have two male guppies. They were really fun fish, but I think I will wait until I live in a place with less strict snail laws to try again with the puffers.
