Hi, I am new. I have two bubble eye fish. Popeye and Dot. I had Popeye longer thn Dot and Dot grew bigger than Popeye. Dot was a baby when i got him or her.Are the bigger ones male??? I mean, dot even has bigger fins and a bigger tail. Please help me. I dont want baby fish.

if you look at their anuses, males have innys and females have outies. also, around breeding time, males get little dots on their gill pltes (which might be hard to see with a bubble eye) but if they do spawn leave the eggs in the tank and mum and dad will eat them up. no chance of babies then

yes and in the males two front fins, he should have a row of dots!
