I have about 30 water striders can they be keped and bred in captivity what do they need for sustenance? They grab fish food but dont seem to eat it just crush it and let it sink do they only eat live food? I wanted to breed them for feeders. Also I found what appears to be a molting but its thicker than I would think it should be do they go thru further metamorphosis? Like just leave their body behind and turn into a water dwelling larva type stage again?
