there? My sister gave me her fish tank with her tropical fish, one of the fish was pregnant (the guppy) until one day I noticed the other fish was following her (she was by the plants) so I put her in the spare tank while I ordered a breeder trap. She is now in the a V style breeder trap but I'm not sure if she is pregnant due to her being followed & hiding by the plants (she looks the same with the black bit by her bum) So my question is how do I know if she has given birth and the other fish have eaten her babies or if she eat them. She is still in the breeding trap just in case.
