Walked by my tank and noticed what I thought was a big pile of fish poo... Was about to get out the siphon when I noticed them swimming around! I put the male and female together in my 29 on the 4th (female had been in the tank for a week or so before cause I couldn't tell males from females at the time), and they already had babies! It was neat watching them suck up the babies and blow them back into their little flower pot cave.
