well...truth be told is that its too large to measure by gallons.....we estimate it to be abt 50 tonnes of water. it is an outdoor pond and i live in the tropics, so heating is no issue. And yes...u do see carp in there.
Nice collection bro! I can't believe how big your Dorados, Widebar, & Rays are. Also I saw your Bagarius and Pacman Cats wow you are a true MonsterFishKeeper! Hardcore! That environment is cool.
other than pacus and irridescents and niger , i see dorardo ( or brycon cant tell) , giant feifeng! and oh a PHAT ST and even a henlei or leopoldi ( dunno bout rays cuz im in cali :| ) but ya! great collection!!!
