My brother's old tank I gave my brother a big freshwater tank for his gigantic arrowana four years ago. He doesn't live here anymore so he left the tank (the arrowana passed away). Could I still salvage the old freshwater tank and then use it for saltwater tank? Or should I drop the whole idea? Coz if not I'll just buy some goldfish and put it on his old tank. I'll just buy a brand new tank. |
