THINGS TO CONSIDER:
An empty aquarium is ONLY an aquarium. *****
ONLY when full of livestock (that is included in the
sale) is a tank considered a SALT or FRESH aquarium.
There is NO SUCH THING as an EMPTY saltwater or freshwater aquarium.
It is JUST an aquarium.
****If you have the EQUIPMENT, ACCESSORIES and /or LIVESTOCK for a SALTWATER hobby, then it is a "SALTWATER AQUARIUM SET-UP."
****If you have the EQUIPMENT, ACCESSORIES and /or LIVESTOCK for a FRESHWATER hobby, then it is a "FRESHWATER AQUARIUM SET-UP."
REHOMING LIVESTOCK:
Check local prices before you buy someone's critters.
Often, buying livestock from a private party is better - especially if they have had (it) for a while w/o problems.
MISC.:
Chips, cracks & leakage are all signs of wear and reduce the prices significantly.
Water marks, discolorations, scratches (esp. on acrylic) and hard-water deposits are usually cosmetic. Because many can be removed with effort, they need not affect price.
Accessories are always great to 'throw in' as a bonus when buying a tank, but pricing everything, stating 'will not separate' and expecting a quick sale - not good. Not many people are not going to use all YOUR stuff if they have other ideas for THEIR new tank. Sometimes people say says " I've invested X amount" I don't give a rat's $#@ what they invested. It's used equipment now and will be sold at used equipment price.
