I can only advise from personal experience.
I don't use a filter at all for the first 2 weeks, and only feed them on microworm for the first week and then on their second week I start them with a little bit of brineshrimp.
No water changes for at least the first 2/3 weeks, only top up the water very gradually with mature pre-warmed water.
You have to be so careful not to overfeed them, so small quantities 3/4 times a day, not large doses. Microworm is great cause it stays alive in the water column for at least a couple of days, whereas BBS only survives for a few hours before dying and polluting the water, which is why I don't feed them that till at least 2 weeks old. Also when you scoop microworm up remember in one brush load you have zillions of the little blighters so once again small brushloads is the operative word.
Small regular feeds, small regular water changes, constant heat and a secure lid to keep the humidity in the tank, so the lid only comes off for very short periods of time.
