With the FLOOD of recent "Out of the Hobby, Fire Sale" threads in the Marketplace forums, I have to ask - Is this because people are just trying to make some extra cash selling their tanks and stock, or is it really that expensive to maintain a "Monster" tank? I only have a 140 gal now, but have plans for a Biggun' in the next year or two. I was thinking once you have the equipment and stock it wouldn't be all that expensive for general maintenence. It hasn't been so bad so far with my 140, but all these threads have got me wondering...
