just saw a shadow in the tank with lineolata, elongata and sp. a lineolata chasing a 20 mm youngster. for 2-3 seconds it seemed to be a single lineolata with 20 adults. half an hour later I could shoot some pictures:





may be I've already forgotten how small lineolatas or spotted look like, but this one is different, isn't it?

interesting that elongata won't chase him away ... does the juvenile pattern work ?
what do you say?
