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,

    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
    the link below. Be sure to check
    the updated comments at "What

     Things continue to stay busy at Select Aquatics,
     and a number of projects are in development to
     be released this Spring / Summer.

     Many species are being built out, and reproduction
     is going well with the Longfin Green Dragons, two
     new albino morphs of the Green Dragons, the
     Ataeniobious toweri, the Ameca splendens, the
     Limia islai "Tiger", the Alfaro cultratus and the
     selectively bred Odessa barbs. The F1 generation
     of the higher white Synodontis lucipinnis have
     reached sexual maturity, and I have started
     breeding them again, to hopefully have fry in
     upcoming months.

     I am working hard to build up my numbers of the
     Xenotoca doadrioi, my selectively bred line of
     the Ilyodon furcidens, the Zoogoneticus tequila
     and the Limia perugia, Boca de Cachon.

     I will be posting Availability Videos later this
     spring as they each reach old enough to be
     shipped, following their upcoming breeding season.
     With a subscription to the Select Aquatics YouTube
     Channel, you will receive a notification when the
     Availability Videos are posted. With an email to, as soon as the video
     is posted, include your ZIP Code, and I will send
     you a quote to ship the fish out to you, with the
     payment information and the next available day
     to ship. When Shipping and available, the block
     for them announcing their availability will be posted
     on this page above.

      I continue to ship the levamisole,
     Rapid Grow Aquarium Plant Fertilizer,
     Sodium thiosulfate and the Perfect
     Batch Brine Shrimp Hatcher on the
     day following payment, and if payment
     is made early enough in the day, I am
     often able to get your order out USPS
     3-5 Day Priority the same day.

     Thank you to all that have purchased the
     Perfect Batch Brine Shrimp Hatcher, and thank 
     you particularly to those that have written with 
     positive feedback. Many of you have told me it is 
     the best Hatcher they have ever worked with,
     and I appreciate your feedback!

     The development of the free Aquariumcareapp
     on freshwater husbandry is moving fast and
     furious at the moment. After 3 years of writing,
     it is currently just under 1100 pages with many
     photos and videos. This easy to navigate
     website will cover just about every freshwater
     aquarium issue. Each of the subjects covered -
     Aquarium Setup, Maintenance, Equipment
     and Equipment Repair, Fish Types Care,
     Breeding, Selective Breeding, Water
     Maintenance, Water Problems, Diseases,
     Foods, Plants, Setting up a Fishroom and
     Shipping are all directly from actual
     experience. Nothing is taken from anywhere
     else, and all is based on the most frequently
     asked questions from over 50,000 emails
     answered by myself at Select Aquatics, over
     the past 13 years. It is still a few months
     away from being posted, and I will continue
     to keep its progress up to date, and will
     announce when it can be seen here in
     this spot!

    The goal will be for other experienced hobbyists
     to contribute and continue to build out the
     information in this aquariumcareapp website.
     Documented efforts that successfully breed
     various species can be included, more
     advanced or innovative care information for
     common or specialty fish can also be included
     to assist other hobbyists. All submissions will be
     emailed to, and
     approved by Select Aquatics before being
     posted. If you would like to contribute to this
     database, please email me at

     I will be returning to doing regular YouTube
     presentations again, where I will answer
     customer's questions. The shows are currently
     being put together, and I hope to see everyone
     again soon as these start to be posted over the
     next couple months. I am also looking forward
     to doing some live streaming as well!

     I still respond to emails from customers and
     hobbyists every day, and will be traveling again
     now that Aquarium Clubs are meeting. The talks I
     offer can be seen HERE, and I will tailor a talk to
     your club if needed. If you are looking for a 
     speaker to bring out to your club, please email 
     me at, and I will 
     send you the information to make that happen!

     BTW, my last property option did not work out on the
     West Coast, so I will be staying in the Denver area
     for the time being-

     Happy fishkeeping!



     Canadian Customers:
     USPS has reconfigured Canadian shipping.

     Levamisole is shipped regularly, but my
     fertilizer has sometimes been delayed by
     Canadian Customs.

     There are 3 ways to ship the levamisole
     (10, 20 or 52 grams) and they are:

     First Class - Up to 3 weeks - $14 + Medication
     6-10 days - $27 + Medication
     3-5 Day Priority - $45 + Medication

     US rates have not changed. (3-5 Day - $9.00)

                    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!

             Christina K. NY


                 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.
