Very new to being a guppy mum, and I got a couple females (4 females & 2 males) from the local pet store. I always thought they were kept seperate from the males but this lady is rather fat looking? Could she be pregnant? If so what will I need to do to keep them safe/ healthy? I won’t be able to keep them in a seperate tank if she does have babies :/ but our tank is 250L so I’m not worried about space just that there isn’t many hiding places in the tank?
