hello everyone. im new to the forum. im a big fan of giant fishes. i had 2 Arapaimas, 2 Alligator Gars and 8 Red Pacus back home(Philippines) before. they were housed in a 250,000 gal pool converted into a pond. unfotunately i had to give them all up when i moved to Canada. im planning to do up another Mega tank in my back yard but as of now a mega pond inside a green house type of thing is the best bet. i like arapaimag's idea but thats seems so much more costly than doing up a pool type pond.
