no ones had one reach adult sizes but 2' seems to be a pretty easy mark to hit with none that i know of at 3'.AngusJB;4180699; said:Just got myself one of these, the supplier has them as psuedoplatystoma sp, but they were clearly a tsnxmarble hybrid, i think they make a nice change from tsnxrtc. Any info on wether they get to tsn sizes or marble or somewhere in the middle?
