so i guess my big fat molly was pregnant after all. i noticed she was chasing something really tiny around the tank. i came closer and saw that she was really thin so i knew right away she had babies. and sure enough i saw 2 HUGE fry. they must be around 1/3 of an inch in length and they already have spots just like their mom. i hope there are more and that they won't get eaten even though they're this big already. this is so exciting!
