Hello everyone.. I am new at all this fish stuff what got me started was I was keeping my moms I think it is a rainbow crab not sure but anyway the pet store told me to feed it guppys. Well I got a few but the crab went almost 2 weeks and didnt want them so i put them in a 5 gallon tank setup. one day we noticed a spot on the belly and tail perfectly round. i googled it and it said it might be pregnant. the fish store said that two. the thing is they are feeder guppys and i think babies. tiny. how do i know? Is there any other fish I can put in the tank? can I post a picture of them so someone can try to tell me if she is pregnant? thank You HEATHER
