20 800 gallon tanks thats insane. I would just take both sell the TV for more than it's worth and get the money. Honestly what would I do with 20 800 gallon tanks I would need to take a loan out from the bank in order to even filter them lmao!!! Are we talking full setups or just glass. Honestly I would settle for a 15K tank and call it a day that is if it is a full setup or I would sell the 20 800 gallon tanks as well as the TV and build the 15K tank with equipment HAHAHA I WINN!!!! Oh and only put one neon tetra in.
