I was wondering if nematodes can be collected off of a dart frog tank wall and dispensed as food prey for carnivorous larvae? This being certain frog tadpoles, and newt and salamander larvae. The thing that worries me is the potential for a pathogen from the darts being indirectly taken in while feeding on the worms. They are basically whiteworms IMO, and seem to be a good food prey(aside from where they would be obtained). I appreciate any tips/advice on this!
