I have had 4 pregnant guppies (that I know of) one birth without me knowing until I seen my angelfish eat one. One birth in a breeder box (I have 9-9 week old surviving fry that are currently in a separate 10 gallon tank, very happy active little things but growing extremely slow). One guppy aborted her fry shortly after going into the breeder box. And one unfortunately died while pregnant. I just put another pregnant one in the breeder box. I'm nervous because I don't want her to get stressed and do abort but I really want to save the fry! As I said, there's no chance of letting her have them in the tank due to the angel fish, and the fry in the 10 gallon are still too small for me to safely put her with them. Any tips? Is it normally a hit or miss?
