Where do they go? Are they getting sucked up a filter tube? Nice pair, be good to get some fry from em.

Try setting up the 29 gal with a sponge filter, ro water, and leds with no substrate and leave the lights on 24 7 tell your ready to move fry over let the pair hatch the fry then wait till they are free swimming then syphon the batch out into a bucket to move them the idea here is to grow plenty of algae that will supplement the rest of their diet that your feed wont cover you can clean the front the tank off to spread aglae to the rest of the tank and so that you can see whats going on in the tank using leds with ro water you should grow forest green to bright green algae that will take over brown algae

The problem is in the RO water. It contains very little or no hardness (Kh or Gh) and the Ph drop below 5 then the fryes just melt down.
Try to separate them in water from parent aquarium or in 50% RO and 50% tap water. Then you will have some hardness and the PH will not drop down and the water will not be acid. Also the fries need some water hardness to build their skeleton structures ;)

Good Luck!

It depends on where your at here i've never had a problem with the hardness of ro water but you can add a mineral additive or some companies call it ro right the reason im 100% against using tap water in my tanks is the ammount of tds in it even though your treating for chlorine and other chemicals in it your not going to get stuff like metals out of it and the phosphates still in it will promote brown algae growth personal I hate brown algae your fish will eat it but it grows way too fast for their grazing habit to keep up with

Here in Sofia, Bulgaria we have tap water with 3-4Kh, around 10-12 Gh, 0ppm nitrates, 0ppm phosphates.
And with fishes that like a little harder water is deffinetly a problem... In my RO water everything is 0.
That is the reason to mix 50/50 with tap water for fry. For adults I use only tap water but sometimes I need to harden it. Or to change water more often.
