Hi as some of you know i inherited two angel fish of my grandads friend.Only had them 2 weeks. As i was watching them this morning i noticed that the larger one ( about 4 inches body width not including fins) was liplocking the smaller one ( about 3.5 inches body width) not agressively them it started sucking at the smaller ones poop hole. Does anyone think i have i male and female if so are they trying to breed. Thanks
