    Default Unsuccessful pair

    Hi all.

    I've had a pair for about 2 months now that lay eggs weekly. The eggs consistently turn white within 24 hours. I've observed the female laying and the male following almost right behind her. (These were a confirmed pair from previous owner.)

    They are in a 20g BB tank w sponge filter. Temp is 83F. TDS down to 75. Feeding BH mix 2x/day. Receiving 90-100% wc's daily with aged water treated w safe.

    Any idea what else could be going on? My thought is that the male is still young and just to give them more time. Their previous owners did have success however so maybe they just need more time to acclimate to my water?

    Thanks a lot.

    I've removed the airstone seem above. This was just when they first arrived.

    Just as an experiment you might consider adding some rooibos tea https://www.amazon.com/Davidsons-Tea...ds=rooibos+tea. A couple tablespoons in a media bag added to the tank should do. A friend with the same issue tried this and it seems to be working.

    Thanks Pat - Worth a try! Is there a thought behind how it works?

    I think it helps to prevent the fungus from forming on the eggs. I have no documentation on this but it is good for the fish and it is fairly cheap.

    Ok I'll give it a shot. Thanks for the advice.

    Your tds of 75 might be OK, but you could also try reducing it closer to 40 and see if that helps.

    Thanks. I will start to go lower. Thing is I don't see ANY eggs hatch at 75. I also am a bit worried about pH crashes but I guess w 90-100% wc's daily it should be fine?

    I would say you are fine re the pH. I believe a crash happens if the nitrification process consumes the available carbonate buffer, but if you're changing water regularly, I would think you are replacing it. You could also be right about the male being young and not really doing his thing yet. Hard to tell.

    I normally do few drops of Methylene Blue to avoid fungal attack on eggs and leave them until they hatch.You could also try moving the cone to a small container/minimal aeration and add some drops of Methylene Blue.So, if the egg hatches then its possibly the water that needs some attention. Good luck and keep us posted.

    Are you sure about the male? Is it possible they are both female?

    Thanks guys. I'm pretty certain they're are male and female given that the previous trustworthy source had success and I (think?) have seen 1-2 wigglers on occasion. I will try the methylene blue one of these go-arounds as well.

    It is interesting how quickly they turn white. Literally they will lay eggs in the evening and by morning every one will be pure white. Then they guard them ferociously for a week, eventually slowly eat them, and start all over. They're persistent at least!

    So this week I tried a few things:
    - brought TDS down to 25
    - added a few drops of methylene blue after the spawn
    - added the rooibos tea

    Unfortunately 80% of the eggs still turned white within a day. It's an improvement from 100% though I suppose. I will find out tonight if any of these actually hatch.

    The Meth blue would only be of use if there was an issue with fungus. The eggs turning white means they aren't fertile.
