I bought 3 male guppies and a male betta in May. They are in a 10 G everyone gets along great. But I've been noticing that 2 of the guppies look pregnant. Can anyone please tell me if these are Male or Female? Also if they are pregnant what do I do? I'm afraid that the other fish will eat the fry, I watched a youtube video and it shows 70+ can come from one birth. Please help.
