I want to create a small pond in my room maybe about 200 gallon. I was thinking to buy some wood in home depot and make a small pond out of it. I look up the measurements length: 55in Width: 40in height: 20in and it measured about 190 gallon. Does anyone know of a cheap way to make it and please let me know how thick should the woods be? If possible under $50 would be really nice and if u have some pic can u please post it? That would be really awesome. If you guys are wondering i am planning to keep a silver arowana and 2 bichir in there. My uncle just got a few small silver arowana about 4-6 inch and i have 2 small albino bichir right now about 3 inch. That is all im planning to keep in that pond and if possible maybe i can also keep a jardini arowana in there too? Please let me know what do u guys think. Thank you!
