How exciting! I've just rushed out to look at ours and disappointingly they still don't appear to be changing. Do you think its lack of food, Sue? You know where they are - I must read up about it.
@pamelaclarke It could be lack of food although I'm not sure what they eat. Ours are in a well established pond so there'll be all sorts of stuff in there. Perhaps they'll eat fish food. I'll ask the expert.
