the egg stripping worked for me on one occasion, but that was well over a year ago and less that half the eggs hatched when all were fertilized. i reccomend putting her i a breeder and waiting til u can see fry in her mouth, then waiting a furthur 5 days for them to strengthen before stripping them into a breeding net to be fed up.
i used a plastic tube (very thoroughly cleaned) that came with duck toys inside (lol) so it was basically 10cm diameter and about 15cm tall. then i made a hole in the bottom of the tube with a stanley knife big enough for the bubbler pipe to fit through nothing else.
i got a bubble maker with an airstone and pipe.
attatched pipe to bubbler, put pipe partly through the hole in the tube.
put airstone on the pipe now in the tube.
i got a pair of tights-material ankle socks and used one to cover up the other end of the tube where the lid would have gone. kept in place by 3 elastic bands.
thats a DIY tumbler in essence, just put in a warm tank and activate the bubbler. obviously put the eggs or young fry in the tumbler then put on the netting lid. and it works ok but nowhere near as good as nature x
