Hi Tomr, I've read and followed your L10a breeding efforts and just like you have had several spawning's and like your experiences have had the fry die off within a week or 2. This last time I separated the 11 surviving fry into 2 batches I put 5 into a tub with some cory fry and placed some used sponges from some of my cory hob filters. so that they get whatever tiny bugs grow on those. For Feeding: I feed microworms daily along with Repashy meat pie (Very small chunks) and see 1 or 2 fry currently... (about 2 weeks old), the remaining 6 - I moved back into the parent tank as I read that there is something that maybe they need to get from the adults in the way of bacteria from the poop or something? When I actively search I see 2 fry that are larger than the ones in the fry tub. The adults might have consumed some or they are good at hiding? It is however very clear from our experiences that they are not too easy to raise! on a related note: My H. hasemani (Columbian Whiptails) just spawned yesterday and I have moved the tube into a marina fry h.o.b deal, have you seen these things? Anyways, I am planning on keeping them in this and see how it goes, for one thing I feel that they will do better in water that is shared with the adults, plus, I am thinking to "overfeed" this baby holder with Repashy and use a well seeded sponge that I will get from a seeded tank so that there are little creatures for them to eat. that's my thought any ways. If I/you have further successes or find a formula that works I purpose we share this so that we are able to succeed with getting them to adulthood! I know that its possible as I see a guy selling 2" babies on Aquabid currently. Good luck to you and please keep me posted. Thanks, Don
I've tried to breed these as well and found this article to be very helpful.
maybe you can use it too.
In my experience the fry do a lot better when kept in a sterile environment, so no substrate, good filtration (think about something used for dwarf shrimp so the filter doesn't make sushi out of your fry). The only 'decorative piece' i had in there was a large Java fern. all the fry hid in there and i always made sure the baby brine shrimp i was trying to feed them, landed in the plant. They don't actively search for food as far as i know.
