Despite having a plentiful supply of live aquatic invertebrates for my larvae I thought I'd experiment with some frozen bloodworms chopped up into small pieces. I found that if I gently flicked the pieces towards the larvae they would be readily snapped up. Obviously this is too labour intensive for so many mouths so my question is - will there be a point in their development where they will feed by smell rather than movement? As adults (these are Pleuros) they eat pretty much anything that smells like food. Do larvae develop this feeding behaviour?
