Select Aquatics                            



    Select Aquatics breeds affordable,
    quality, specialty tropical fish for
    hobbyists and conservation
    research. Most are not often
    seen and many are endangered  
    or extinct in the wild. This site 
    is also a one stop place for 
    fishkeeping information on
    how best to keep these

    If you are keeping an aquarium,
    you have the opportunity to help
    preserve species that are about to
    go extinct in the wild. As well, due
    to increased export restrictions,
    many species are at risk of
    disappearing from the hobby.
    The fish offered here are hardy,
    generally not difficult to care
    for, and may depend on
    hobbyists such as yourself to
    maintain their availability. 

        Select Aquatics of Erie, CO.

        Select Aquatics maintains a
        fairly consistent collection
        of species/lines that are
         bred here and posted as
        available. If you wish to buy
        anything on this page, or wish 
        to see a new species offered, 
        please contact Greg Sage at .

    Ordering new species you've never
    kept from someone you don't know
    with water different than yours can
    be scary. Some assurance that in
    6 months the fish will still be doing
    well would be ideal, particularly
    since many of these fish are rare
    or hard to obtain.

    From your first email to inquire
    about ordering until the moment
    they arrive, we will keep in close
    touch to answer any questions you
    may have so that you know exactly
    what you are getting, and precisely
    when they will be sent. Care
    information for each species is
    also provided Here.

    Postage is never overcharged, and
    extras are nearly always sent with
    carefully done, professional
    shipping. To help ensure they do
    well for you, a Care Guide is
    provided for each species from

     Efforts to downsize the number of species
     here and build out those in greatest demand
     is going well. Availability Videos are being
     completed for each species, and the current
     lineup can be seen HERE. For 13 years I
     offered 30 species that often sold out shortly
     after being posted as available, and a year
     might pass until they were available again
     (as most species here breed seasonally).
     Today there are now 10 species, and where
     many were maintained and bred in 2-4
     29 gallon talls, more tanks are now devoted
     to each species, hopefully allowing for
     greater availability into the future.
     For example, with breeder tanks, fry and
     grow out tanks, there are now 7 tanks
     of A. toweri, 11 tanks of Z. tequilas.

     With USPS overnight delivery suspended
     or delayed over the holidays, in combination
     with rougher handling, I will resume shipping
     the second week of January, weather and
     temperatures permitting.

     Over 45 boxes of fish were shipped this fall,
     and many thanks to each of you that are now
     enjoying your new fish!

     Over 250 Odessa Barbs were shipped this fall,
     and as those remaining here put on size, groups
     of 2-4 Month Old Unsexed will be sold, until
     offered in groups of two or three young pair
     (+1 extra individual), which will be kept up
     to date in the block above.

     The Ataeniobious toweri, the Blue Tailed
     Goodeid, is available now in both groups of
     six or nine 2-4 Month Old Unsexed, or
     groups of two young pair (+1 extra individual)

     The Ameca splendens are doing well, and
     available now in groups of six or nine 2-4
     Month Old Unsexed.

     The Alfaro cultratus, the knife livebearer,
     are doing well, and available now both in
     groups of six or nine 2-4 Month Old
     Unsexed, or young sexed pairs.

     Species that are not ready to be shipped,
     because they are sold as sexing out pairs,
     and currently too young, include the
     Zoogoneticus tequila, Ilyodon furcidens
     (The Trout Goodeid), and the Xenotoca
     doadrioi. Fry numbers have been good for
     the tequilas and furcidens, with slightly less
     production from the doadrioi.
     Their Availability Videos will each be posted
     as they are ready, starting later this spring.

     The Limia islai and the Limia Perugia ,
     Boca de Cachon are each doing well, and
     many were shipped this fall. I am building
     them out to again offer groups of six or
     nine 2-4 Month Old Unsexed.

     The Longfin Green Dragons are doing well,
     and are a slower growing hybrid. They are
     currently about an inch long, and sorting for
     finnage and color are still ahead of them.
     There will be 160 sold this year, and I will
     and I will continue to post their progress
     here, and announce here when their
     Availability Video will be posted,
     mid to late spring. A price has been set,
     and they will be $270 for a group of 4+1
     including shipping, and roughly half of that
     will be the shipping cost.

     The recently returned Xiphophorus Montezuma
     group of fry are now being sorted for the
     best breeders going into next spring, and
     their fry production will determine when
     limited numbers of 2-4 Month Old Unsexed
     will be offered. This is a fish again
     disappearing from the hobby, and I will be
     working to build them back out again, but it
     will likely take up to a year. Nearly a
     thousand were sold over the past 13 years,
     and they should appear at
     until I again have them available.

     Many of the rarer species here are quickly
     disappearing from the hobby. Please
     consider keeping and breeding each of these
     species long term, and be sure to distribute
     them to other responsible hobbyists.

     I have rebuilt the Synodontis lucipinnis
     breeding area, including larger tanks,
     and the higher contrast F1s born
     here about two years ago are now old
     enough to breed. I will start spawning
     them over the next couple months.
     It will take a few months before fish at
     roughly 3/4" will be available, and they
     will be posted above following an
     Availability Video when they are ready
     to be shipped.

     The availability of any species will be
     kept up-to-date on this homepage,
     in the blocks above.

     I generally respond to my emails within
     24 hours, and do have a few spots still
     available to come out to speak to your
     local club in 2023. If you would like to
     explore making this happen, please
     email me at,
     and we can discuss it!

     Thank you-

                    Mr. Sage provided me with the best experience I could've asked for. The wonderful fish he breeds are priced
               very affordably, and are super high quality.

              He always responded to our emails swiftly and was extremely helpful with any questions and concerns we had.
              His packaging of the fish was phenomenal, and all (even the extras!) arrived across the country in excellent

              They are beautiful, healthy, and active. it was incredibly stress-free as I knew I could trust the process.
              Despite a small delay due to the USPS, Greg quickly assured us that the fish would be fine.

              Mr. Sage has a great reputation in the livebearer hobby, and I can say he has totally lived up to that
              reputation for me and I'm looking forward to ordering from him again! I seriously can't recommend him
              enough. Thank you for all you do for the hobby, Mr. Sage!

                 First, off thank you for the beautiful fish. Every time I receive a new species from you I am always surprised by 
              how much more beautiful they are in real life versus the picture. The Alfaro cultratus you sent for example are far more 
              stunning than any picture I have ever seen of them. That includes Google image searches.

                Hi Greg,
             The Odessa barbs are here, in GREAT shape, and currently 'acclimatizing' in a 5 gallon bucket with my own 
              graduated drip system.

             Thank you very, VERY much for your attention and care and patience with me throughout this process. I've been 
             receiving fish via express mail for 30 years but your packing is a whole new universe from what I've ever experienced.

            Thank you again for the 'bonus' fish which I counted as 8 but my wife insists is 9. She also could not believe the packing
            or condition of the fish. Also, thank you for the anticipated forwarding of the rebate check for the excess shipping charge.
            When everything stabilizes, I'll forward some pics. Again this has been the best fish purchasing experience I've ever had.
