I think I have a couple gravid female harlequin rasboras, but I don't know if I have a male or the breeding situ. is right. Can the female become gravid even if breeding conditions are not right or there is no male present? If she does, does she lay the eggs or retain them? I'm trying to discern whether they are gravid, bloated or fat. Their bellies look like tiny lumpy marbles are inside and very dark strip from chin to tail along her bottom side. She hangs around the bottom, sometimes isolating herself, which I know is not normal, but swims around actively too. I've seen them fan the bottom of leaves, but no one is laying eggs or getting thinner. I have 9. One died for unknown reasons with in a week of getting them.
