What food do you use? There is egg yolk from hard-boiled egg that you can mix with little water and squirt to the fry. A tank filled with riccia plants provide the fry some microscopic organisms to eat particularly infusoria.

I'm ready for the pressure.

im using liqifry #1 what im doing is mixing it with a teacup of aqarium water and pouring it down the tube to the location of the fry still no luck the fry seem to eat but still after 3-4 days there all gone my both species produce batch after batch of fry with none reacing maturity would removing fry from the parents into a smaller tank work?
...the julies tank contains big mystery snails could these be eating eggs and fry?

Worth a try. Sponge filters are recommended for fry tanks.

Yes, I think so. I'm trying to search for a thread I remembered where Chris discusses with other snail enthusiasts regarding the mystery snails who are able to swoop down on unsuspecting fish particularly the part where a snail managed to grab the fish's tail but the fish was able to escape. Eggs will, of course, be eaten by almost every aquatic creature.

thanks since writing this thread both species are together in a large tank and the snails have moved both are breeding again i found when removing the julies that there WERE some young in the tank the main problen with the julies may have been the unpredictable nature of the smaller tank+snail menace ... thanks for the input

When I had cory eggs I had to remove them or the parents ate them. The first 2 batche sI had hatch, I let them go when they were about 7 days old and no one them survived. Then I watched really close and I actually saw the adults chase down the babies and eat them. I was shocked. I would imagine that the cories are making snacks of the fry. As for the mystery snails, I have heard they are egg eaters so they could also the culprits. As for eating the fry, they would only eat them if they were dead or if they somehow caught them. With as slow as a snail can be a fry might not react until it was too late.

the babies that i transferred to the larger setup were quite small but big enogh to resemble mini julies i also found a few very tiny fry perhaps the parents had turned on the older fry to protect the new? which were unable to be chased off due to space constraints

I finally just kept mine in the net breeder for 4 weeks and the adults finally left them alone. I wonder if we forget to feed the adults enough that causes them to eat the fry? I know it took a lot of bloodworms to get mine to finally lay eggs and once they started I didn't feed as much to keep the tank from getting polluted. Maybe it was a lack of protein or something like that.

its difficult to get food to the adults and babies due to the nature of the spots they pick i found that i can use the gravel cleaner in reverse to blow food to the babies under a large concave rock , the new setup seems to have helped i see the julies much more often now with any luck at least a few fry will reach adulthood its all a learning curve

I am breeding my julis in a 15g tank with crushed coral substrate, billi-filters (a sponge filter), and large snail shells (apple snail shells to be exact) and 4" clay pots in so the parents can have a choice in choicing their abode. After the fry have hatched, I feed infusoria and microworms. As they get larger, baby brine shrimp are fed.

I have never had the problem of losing fry to predation of the parents (knock on wood), although I have heard of such behavior. You may try removing the parents after the fry have hatched to prevent predation.
