ya i tried to sell one of them . had an add up for a while still up actually even had the price dropped as low as 200 bucks . which is supper cheap .had a few people interested but most were in the states and looking for me to ship it .
maybe i will bump my add up again . or i do have the option to take it to a fish store and sell it on consignment maybe thats a good option .
as far as upgrading to a larger tank im pretty sure there fine in this tank untill 2 feet at least even if it ends up being just one of them . which is probbably a good few years off
