To our valued customers: 

We will continue to operate as best we can under the circumstances. We know that your operations, large and small, rely on timely delivery of food. However, our utmost concern is for the health of you and your families, our dedicated employees and their families. So please bear with us as we try to make the best of a bad situation.

To limit exposure in the workplace we will be closed on Fridays. 

Shipping transit times are currently not guaranteed by FedEx.  Please be aware that prolonged severe weather is causing transit delays across the US, not just in affected areas.

Winter weather has created hazardous conditions across the US and has caused substantial disruption at the FedEx Hub in Memphis.  FedEx is working hard system wide to clear the back log of packages while keeping employees safe.

Until further notice, we will ship all frozen orders on Mondays and Tuesdays.
Stay healthy ansd atay safe!

Cool Mix

"...I just wanted to let you know that I have been using the Zooplankton Plus Flakes on my discus and freshwater angelfish with tremendous results. I used to feed them un-named competitor, I now use the Zooplankton Plus flakes only. It results in excellent color, growth and breeding. I also raise IFGA Show guppies. For them, I put the Zooplankton Plus Flakes, Earthworm Plus and Phytoplankton Plus Flakes in a blender and pulverize them into meal. This makes an excellent guppy food mixture...I really believe BSD has the best flake foods around." S.C., Kearney, MO

COOL MIX (formerly Tropical Flake Medley) is a careful blend of FIVE of our most popular AQUANIX formulations - our mysis and DHA-enhanced COOL MYSIS, our krill-rich COOL CICHLID (formerly Zooplankton Plus), COOL COLOR - a brine shrimp backed color-enhancing formula with over 600 ppm astaxanthin, COOL GARLIC with proven immunomodulators and the benefits of allicin,  and COOL GREEN (formerly Phytoplankton Plus) made with spirulina, kelp, chlorella and schizochitrium. This powerful blend of marine and plant-based protein formulations make COOL MIX a widely accepted, multi-faceted diet used for both freshwater and marine community tanks.

COOL MIX is a robust, full-bodied flake, but can be ground up and used for small and medium-sized fish.


We employ a different process to make our AQUANIX line of premium flake diets. COOL COOKING METHODOLOGY helps to ensure that the key ingredients that comprise our AQUANIX diets remain intact from start to finish. Because many essential amino acids, vitamins, flavourants, lipids and beneficial bacteria are heat labile, conventional flake processes destroy or alter the very qualities a formulator (or fish breeder) want to see in a premium fish diet. That is why we are willing to spend a little more money and a little more time for a processing technology that operates at half the temperature of conventional flakers. We're confident that you'll see the added value in your fish, in their health and in their appearance.

COOL MIX, like all AQUANIX Flake Diets, not only has exceptional water stability, but it also contains viable beneficial bacteria that can facilitate the conversion of fish waste and uneaten food into harmless microbial biomass and carbon dioxide -  so you'll see an improvement in your water quality as well.
