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.

    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

               Do You Have Trouble
              Keeping Livebearers?

         There is a very Common Disease in the
         Hobby that causes many Livebearers to
         become thin and perish. A small parasite
         exists in our aquariums, and often comes
         from where we obtain our Fish, and it
         primarily affects Guppies, Swords, Platies
         Mollies and Limias.

        Called "Livebearer Disease", this is
        often why many have trouble keeping
        livebearers. There is only one drug that
        is effective at treating it -
        Levamisole hydrochloride.

        Levamisole is also totally effective at 
        eradicating camallanus worms and
        other minor pathogens.

        This Drug is not Available from your
        Local Fish Store. Various sized
        packets are offered below with a
        measuring spoon. A 10 gram packet
        will treat 500 gallons. See more info
       HERE and in the right column below.

       Ilyodon furcidens Progress      

    There are now Twelve 30 and 40 gallon
    breeder tanks devoted to them, 10 tanks
    are Breeder groups, each of 5-10 pairs
    that have finally started producing fry,
    and there are roughly 150 fry at this time.
    A customer has contacted me that he has
    them from a previous generation, and will
    ship them to anyone looking for them.
    His Contact Information is at the bottom
    of the column to the left. I will Post an
    Availability Video for those here as soon
    as they are ready to be shipped,
    announcing when they are ready.

       Ameca splendens are Available

       The Ameca splendens have done well
       this spring, and a limited number of groups
       of Six 2-4 Month Old Unsexed are available
       at this time.

       Everyone Else!

       The Ataeniobious toweri (the blue tailed
       goodeid) also continue to do well, and
       limited groups of young pairs and groups
       of six 2-4 Months Old Unsexed are
       currently available.

       The Zoogonotecus tequilas continue
       to do well, and a limited number of
       young pairs are again available.

       Due to the reintroduction effort
       discussed in their recent Availability
       Video (Select Aquatics Available,
       Z. tequila 2024), the Z. tequila has
       had their population designation
       changed from Extinct In The Wild
       to Threatened. That is Very Good

       The Xenotoca doadrioi are slowly
       starting to produce this spring, though their
       numbers are not yet strong enough to post
       them for sale. Numerous breeding groups
       are being set up for them, and though I
       cannot say at this time when they will be
       ready to ship as either young pairs or
       groups of six young fish, I am working
       hard to build them up, to have them more
       regularly available in the future.

       The Limia islai "Tiger" are doing well,
       and will be available again in groups of
       2-4 Month Old Unsexed soon.


       I have been in contact with the The
       Longfin Green Dragon wait list, and hope
       to ship top quality young sexed pairs later
       this fall. There should be many be many left
       over, and they will be posted for sale here
       once the waitlist pairs have been shipped.

       Lastly, be sure to check out the Interview
       and Fish room tour videos of the

          Greater Availability of Species!!

        When Select Aquatics began, I posted
        the letter to the right to all serious
        hobbyists, to consider taking on some
        of these exceptionally rare species,
        maintaining them long-term, and
        distributing them to others, so they do
        not continue to disappear from the hobby.

        A few have come forward, and I was
        recently very pleased to tour
        Ed's Aquatic Exotics, outside of
        Pittsburgh, to find that Ed is working
        very hard to keep and maintain a
        number of species no longer carried
        by Select Aquatics. Known through  
        emails as we share the same concern
        for optimum fish health, his lines are
        well established and robust.. Check
        out his site from the link to the left
        and HERE - - EdsAquaticExotics.


       I have also added my friend Marshall
       that has been supplying packing supplies
       to Select Aquatics for the past 14 years,
       most importantly providing breather bags
       and heat packs, and his site can be visited


       Please check out the other links to 
       the left and I will be adding more
       recommendations in coming weeks!

                    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.
