yeah ive had him about 18m and he was already grown so im guessing he is close to 3yrs by now!-) will be sad when he does go, even considering my monster fish he is one of my faves, yes when i tap the glass with my nail he comes out to be fed. he is loving the pothos and has started a nice bubble nest around it now. ive tried to breed him but he has always fought with my female double tail.
