I got a lung fish a couple months ago...i think he's about 9 mos or a year old, and he's 13" long...right no we have him in a 30 g long style tank and are upgrading next week to a 50g long tank.. we feed him shrimp and algea pellets, and feeder fish but he never eats them and they r getting 2 big 4 him 2 eat... the guy at the lps didnt' know much about him or what he was but i researched and researched and i know he is a marbled african lung fish and he's gonna b huge... the thing is i cant find anywhere what water temp he is supposed to be in.... right now he is at 28 degrees but i want to turn it down a bit and add my other goldfish to his tank... anyone here know more about these beautiful creatures? also how fast do they grow and how big will he get?
