Hello all! I see this is a common question here.... but I have to ask for myself as I am new at this! I ordered some guppies online, and I'm wondering if they are pregnant. They both have very dark gravid spots. I've had them for about two weeks now and their bellies seem to have gotten a little bigger but I can't be sure. I also noticed tonight that the blue one was getting pretty aggressive when I fed them. She was chasing the others away from the food on the top and the others just ate from the bottom. I've not seen that until today. Is it common for guppies to get aggressive when pregnant? (if they are) I'm posting two pictures of the two guppies I suspect are pregnant. The top is of when they first arrived two weeks ago and the bottom is of them today. Any feedback is very much appreciated! Thanks!
