I have no trouble getting my killi's (albino f. gardneri) to produce fry - but they fry never want to be weened off of suspension / particle food. They don't like flakes, live worms (?! wtf ?!), any of that. They starve till they die, after they get too big for suspension food. I even tried large chunklets of boiled egg yolk (as opposed to puree'd egg yolk, which was the suspension food).
Any suggestions?
