Wow, I know just how you feel! A female redstripe did the same thing for me this year! I bought her, she started getting fatter and fatter and a few months later... 16 babies!! They are actually a breeze to work with. Try offering them little fish pieces tomorrow or the next day. If they do not take them, and you can't get guppies, start them on rosies. They are better than goldfish and better than nothing, and then you can manage to quite quickly switch them off the rosies (it only took me 1 feeding of rosies before mine ate ANYTHING that smelled like fish). Wait until you see how FAST they grow. it's like lightening!
