Select Aquatics                            

 
   

 

 

    Select Aquatics has been
    shipping rare and specialty
    livebearers to hobbyists,
    public aquariums and
    research facilities for
    17 years.

    Today, we focus on the
    popular selectively bred
    species developed here,
    that serve to introduce   
    Goodeids and other types
    to hobbyists, while still
    offering the highest
    quality, pure wild
    stock of other rare and
    endangered species.

    All of the species currently
    offered, and their availability,
    will be kept up-to-date on
    this homepage.

    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

           Rapid Grow Aquarium Plant Fertilizer is Back!!

       After 6 months, my local supplier has located a new source
         for the original ingredients, and I am able to offer this amazing
         aquarium plant fertilizer once again. It is the same fertilizer,
         sold in a 10.5 oz. quantity, a single order will dose over 40,000
         gallons! Many have written how this fertilizer has quickly boosted
         and improved their aquarium plant landscapes.

         Not like any other aquarium plant fertilizers sold in stores, it
         contains the highest quality, food grade hydroponic fertilizers,
         tested for over 3 years here to dial in the dosage. Sold by
         Select Aquatics now for 15 years, hundreds have been sold with
         many enthusiastic responses.

         It's cost is still far below the cost of comparable fish hobby
         fertilizers-

         $35 (Fertilizer) + $10 (Shipping) = $45

         Make Payment to the account name
         selectaquatics@gmail.com at Paypal.com,
         and I will ship the following day!

           The Odessas are doing very well, and I am
           about to post a video on the new automated
           system built to spawn them. Sales of the recent
           batch went well, and a new group is being started 
           to be available as temperatures come back toward
           the Spring.

           The tequilas, splendens, and Tiger Limias
           also continue to do well and are currently 
           available

A For many years I carried the especially large
         (occasional males that attained 6.25 inches,
         nose to swordtip) Helleri Rio Otapa swordtail,
         from Rusty Wessels original collection. Many
         hundreds were shipped out to the hobby,
         However, I am being told that they have
         become difficult to find, and may be
         disappearing from the hobby.

         I was able to locate my original population in a
         fishroom across country, and a small group are
         now doing well here. I am hoping to receive fry
         from them again soon. Hopefully I should have
         them available for sale by possibly late spring /
         early fall of next year. They will be posted
         above when ready to be shipped.

                        Latest Select Aquatics Fishroom Video!

     
                     The first Fishroom Video since 2019 was just
                      posted, and with encouragement from various
                      customers, I worked with a big band ensemble,
                      performing a solo piece arranged and recorded
                      specifically for this video. You can let me know
                      what you think! I spent most of my life touring
                      and performing as a trumpet player, and it has
                      been a pleasant experience to combine that
                      with Select Aquatics!

                             You can see the video HERE!

                                     WARNING to Goodeid Buyers!!
                                                                                Please Read!!
    

                          Goodeids require that they be maintained and bred at temperatures below 76°- 77°.
                          Many Goodeid species, when exposed to higher temperatures, generally around 80°
                          or above, can be sterilized permanently, sometimes when exposed for as little as
                          just a couple days. .

                         I answer questions each day from hobbyists looking for information on keeping these fish,
                         and continue to be contacted by hobbyists that have bought goodeids from other well
                         known internet sellers. They will sometimes maintain them at inappropriate water parameters,
                         such as high temperatures, inappropriate pH, and outlier Hardness. This can resulting in fish 
                         that arrive alive, are not healthy, and/or will not breed as a result of their previous care. Be sure 
                         to ask your seller before purchase if they are maintaing their fish appropriately!

                        Temoeratures can be no higher than 76- 78 degrees, pH should be roughly 7.2 - 8.0, with
                        100 - 250 ppm hardness. One prominent seller maintains his fish at 79 degrees, 8.4 hardness 
                        and 300 ppm hardness! They may arrive alive, and may survive for you, but you may never see
                        reproduction.

                        Efforts by myself to contact sellers with customer concerns have gone unanswered. Choose
                        sellers that both know well and take pride in the fish they keep, sellers that produce healthy and
                        appropriately priced stock. If they claim to only have a few fish, and charge two or three times
                        what I charge for them here, then don't respond to emails when asking for information, you  
                        must seek out another source.            

                        Do not assume that because someone is selling these fish, or has posted a few youtube videos
                        that they know about the fish they are selling!

                       The sellers listed above on this homepage know Goodeids, their proper care, with many years
                       experience keeping these fish. Knowing everything they can is their first priority, while always
                       priced appropriately, with much information and genuine concern that the fish you receive will
                       do well for you.

 

                      Thank you -

                  A Quick Word about the Past, Present and Future of Select Aquatics!

                   

              I began breeding and selling my own lines of guppies to local pet shops from my bedroom 
           in eighth grade. I served as Chairman of the American Livebearer Association from
           2000- 2004, and Select Aquatics was started in 2008, after selling fish at ALA conventions.  
      

              When chairman, predictions of many of these fish disappearing from the hobby came up
           frequently, and species were starting to disappear. The goal of Select Aquatics was to obtain
           many of the most highly desired fish, build them out, and offer them to the hobby so that they
           were not lost, as affordably as possible. My rates were set to meet overhead, and I have
           never drawn an income from Select Aquatics - Profits were simply put back into better foods,
           improved equipment, better tanks, etc. 

           When I would get to a point where after many hundreds, or over a thousand were distributed  
           out to the hobby (such as with the Xiphophorus Montezuma and the Poecilia velifera) and  
           shipped, I then moved on, providing tank space for new species to build out and distribute.
           30 species at a time were maintained and shipped from here for many years. Recently I  
           have cut back, so that I can provide desired species in greater numbers, more
           consistently throughout the year. It is then up to the hobby for people to breed them, and
           offer them for sale at sites such as www.Aquabid.com, so they do not disappear.

           I have always enjoyed selective breeding, and have introduced six new lines to the hobby
           over the past 30 years, and with the exception of the Ilyodon furcidens, which is not
           rare or endangered in the wild or the hobby, I have never selectively bred any of the 
           Goodeids or the rarer fish here
, though it is commonly done in Europe, where many  
           beautiful varieties of the Characodon audax, for example, are available. Many of the  
           populations here have been breeding consistently, fully acclimated to this water and  
           are fairly homogenous genetically, breeding at their potential since 2002 - 2004.

           I am building out species such as the Zoogoneticus tequila that are exceptionally rare,
           and not widely available in the hobby. I plan to continue working on the other species that
           were selectively developed, such as the Odessa barbs and the  Ilyodon furcidens,
           while continuing to focus on the pure lines of the wild livebearers that continue to do
           well here.

           Over the past 15 years, Selectaquatics has now carried 46 different species, and the
           care information on each of those species, from when they were being sold here, is
           maintained at the link in the left-hand column above. If you maintain any of these fish,
           please breed them and distribute them to others! If you do not, many of these species,
           even some of those listed above, could be gone from the hobby within a few years, and 
           in many cases, it is no longer possible to go to their home countries and collect them,

           Thank you for considering Select Aquatics, and I continue to respond to emails each
           morning, discussing species and fish problems, and at this point, after over 75k emails,
           I have probably written with most of you! I continue to speak to clubs each year, and if
           I am ever in your area, I will look forward to meeting you!
