I've never fed live food to my fish and I don't think its a good idea really. There's always the risk of introducing unwanted bacteria and parasites and there's plenty of freeze dried foods out there that do the same job.
Everybody I've spoken to about live feeding has advised me against it and I think it's best to take the safer option to help keep your little guys/gals safe. Your fish are too beautiful to put at risk. Keep up the good work
