I have one male and three females left, used to have 6 females, but Reyna and Orion got a little hungry...
As of my last count, they have had 4 batches of babies in a little under 3 months, and I know another one is pregnant. So far none of them have been eaten that I can tell, I think Im only missing one and I found it in my filter when I cleaned it... guess the fish was too stupid to stay away from the filter.
But basically they are hardy, and easy to breed, the only reason I can come up with why they have lived so long is that Reyna and Orion dont like their tales cause it makes them look so big, they do seem to enjoy chasing the babies around though, which is very good exercise and they havent caught one yet cause they are so small and can get into so many small areas that my turts are now too big to get into after them.
