ok listen, they would hatch in two days.
i would start with egg yolk, boil an egg use the yolk when they start swimming in the 2nd or 3rd day of hatching.
i used the potato experiment, but it smells 0-0 if you want to know peel a potato, use the inner potato not the outter, live it in water for 2 days and remove it WARNING smells bad. another for the first week is getting live plants to have infusoria (like the potato) and fries would eat that. also do not feed fries when they hatch just feed them the 5th day of hatching (they should be able to swim by then)
sorry to hear that. get a heater or so to keep them warm.
tend to the parents too, males would be kept with the eggs until they start swimming, remove the male after wards, he would get depressed so give him care. the female would be torn up, just fix that she isn't really sad about anything. do CAREFUL moving since the fries will need space, remember not all live. i lost my first 2 spawns.
if you are not able try to contact a breeder and see what they say about this emergencey they are wayy to young for travel, i would love to take them i live in IL.chicago also am a beginner breeder so i may help if you decide to keep them
if i would be able to ship fries (when they are able to swim) is to put live plants, heat pack(s).
sorry to hear about that, good luck
