Water change water change water chage. Im not sure if jd will care for their young or not if they do life is easy. Do a water change. Take a bunch of flake food place in a ziplock bag and crush in to a fine powder and use this to feed babbies about 4 or 5 times a day. To feed just take a pinch between thumb and forefinger reach into the tank about half way and grind your thumb and forefinger together to disperse then wiggle your fingers a bit to stirr it around a bit. Do this above the babbies.
Set up an empty grow out tank and use water from your breeder tank to cycle quicker. Water changes should be at least once a day, this will help prevent deformiteys ect... as they get a little bigger you can start the feed with brine shrimp either frozen or grown yourself. A big pop bottle and air stone is neede here. I grow brine shrimp and feed to my breeders too. When feeding flake i use a high protine food.
After a month or so, when they are not so delicate transfer to grow out tank. If jd's dont care for their young you will want to get then into a tank asap. They can be transferd using a turkey baster if need be, but you will likely kill a few in the process.
I can not stress enough the importance of water changes, once a day mininmum. Ammonia builds quickly due to amount of feedings, its hard to clean substrate cause babbies will hang on the bottom. When they are transfed to an empty grow out tank it is easier to vac bottom as you can see excess food and you can pull the tube off the siphon end of substrate vac and just use the tube to vac so you dont suck up babbies.
Hope this helps and good luck.
