Rasboras breeding! Now what?

So I thought one of my Harlequin Rasboras was constipated but its actually a female and shes gravid lol. It also seems that I have 6 males and only 1 female. Its getting pretty heated in there! They've been trying to do the upside down boogie under my Anubias leaves all morning.

What do I do next? Let the eggs and fry fight for a chance on their own? I don't really have another tank and I wasn't expecting them to start breeding so soon. Apparently these fish are difficult to breed!

Thanks

Edit: its 2 females and 5 males upon further inspection. Both are being harassed

I’d try to get more females ASAP. The stress will eventually kill the 2 you have.

Get an floating egg breeder and put the plant in there, good water flow, low light and drop the PH to 5.5 if it’s high raise temps to high 70s. This all might be an issue if you have other fish, but they should hatch in a few days but very sensitive. You can addmethylene blue.

Rasboras are very hard to hatch and take care of but it’s possible. You could just leave them too but I highly doubt they’ll make it.

Yea none of my tank conditions met the breeding standards but they did it today anyways. Eggs all over my anubias, which they then immediately ate. I doubt the first batch was viable anyways

Everything I've read about harlequins says the ratio of m to f doesnt matter at all, can you provide a source? The only reason is that I want to make sure its accurate before making more changes

Source is simply experience. I’ve bred all kinds of tetras. You’re right they’re not as finicky as livebearers, but it still stresses them. I always kept an even ratio at minimum with better success, gaged by females showing more bold colors (they can be more colorful than you’d think, though not like a male). Also depends on the tank size and arrangements.

When I had 3 to 1 ratio my females were more dull and stressed...had 8 in a 50 gallon planted tank, granted I had prime breeding conditions...but sounds like you do too incidentally.

Thanks, I'll look into adding a couple more females once my tank stabilizes. Parameters stay at 0 for a few days and then I get a small ammonia spike. All good though. My tank does seem ideal for breeding but it doesnt match the parameters quoted online, ie too cold, Ph too high, etc. Guess they dont care
