almost a year ago, all I had was 3 harlequin rasboras in a 10 gallon aquarium. this was the start of my fish-keeping. a couple months later, I remember seeing some eggs. they were small, round, and white. there were about 10, maybe. there was also snails in that tank, but their eggs were goop with eyes. if there were eggs once, how can I breed them more? and how can I keep the eggs alive? I now have 5 rasboras. what are their breeding conditions?
