These 2015 T verrucosus larvae are almost a year old now, but they show no signs of morphing yet, even though they are well over 10cm and still growing!
All the rest from their batch morphed in October at a much smaller size and were fed the exactly same food and kept in identical water chemistry, but were given their own 15 gallon tank, whereas the giant ones have lived with their parents the whole time. I can only think it's the water depth of 600mm and/or the relatively large water volume that's kept them from changing? If anything I would have guessed the ones that live with their parents would be first to mature due to the competition for food with the adults, not the other way round!
The pic with the ruler isn't very scientific I know, but it's rare to see them out in the open like that.
Has anybody else had Tylo larvae get huge?
