helping aquarists become more successful since 1931
  • Guidelines

Note: This auction section is currently under development. Any items entered during development is not part of the auction and will be deleted before we open up the next auction.

Only logged-in MAS members have the options to submit items and to bid on each item. If you are a paid member and unable to access these features, please use our Contact Us form.

How it works

  • week before the BAP/HAP auction: MAS members may use the online system to list the species they've bred (BAP) or propagated (HAP, plants). 
  • Wednesday evening: All items need to be listed at least 24 hours before the auction closes.  Fellow members may bid on these items until bidding is closed.
  • Thursday evening at 10:00pm (Central time):  bidding is closed.
  • Friday:  Winning bidders will submit their payments here:  We will accept checks when you pickup, but we prefer you make payment online.
  • Saturday: Those submitting bags need to drop them off between 10:00am and noon.  Winning bidders may pickup their bags from noon through 2:00pm. Both parties will be sent the address of the drop-off/pickup location, which is near our normal meeting location (Roseville, within a mile off of Hwy 36 & Dale).


  • If you are unable to drop off your bags at the given time/location, you should not be submitting listings or bidding on items.  If you fail to pickup your items in a timely fashion, the items are subject to being forfeited.
  • Standard BAP/HAP rules apply:
    • one must be an MAS member to submit and to bid.
    • BAP fish should be at least 60 days old and at least four being submitted.
