Harlequin Rasboras Spawning?
Hey.. I just recently started up a new tank and since I was pretty much done with planting it, I thought I'd give some fish a try since my adf were doing fine. I bought five harlequin rasboras this weekend and I think they're spawning. At least, from what I've read, it sounds like it. They're fluttering around eachother and then swimming upside down beneath some of the plants together. Problem is, I don't think I really want any fry in my tank, so I guess my question is first, am I correct in assuming they are trying to spawn? I don't think I have seen any actual eggs, but they are repeatedly going back to the same plant and swimming upside down together at it.. should I be able to see the eggs? Will the other fish eat the eggs? Or my frogs or snails?

sounds like spawning. It could also be a 'dry run' where the adults exhibit spawing behaviour but aren't actually laying eggs. If they are laying, its likely that the adult fish will eat the eggs or fry when they hatch. I know some people on here have had occasional fry survive in a community tank but this has been in large, densely planted tanks with places for fry to hide like java moss. One the whole, it's unusual for the fry of egg scattering fish to survice without some intervention by the fishkeeper.
Ok, thanks for the info. I didn't really think they had much of a chance for survival. I wasn't trying to get any fry, but I do sortof feel bad if they'd be eaten. However, I don't have another cycled tank the adults could be moved to or anything anyways, so I'm limited on what I can really do.
They're 'spawning' again today.. is there any particular reason why they do "dry runs"? Are these fish going to try to breed all the time, or would the introduction of another fish species inhibit that? These were just the beginning of stocking anyways. I'm just hoping they won't start to be aggressive or something because they are spawning.
Harlequins won't get aggressive - some species, like cichlids, will guard their eggs and fry aggressively however
My glowlight and pristella tetras show courting behavior all the time (shimmying next each other) but i've not seen them egg laying yet
