The Northwest Arkansas Aquarium Society is an organization formed to bring together the aquarist community in Northwest Arkansas and the Ozark region. Our members range from new hobbyists to long time breeders, and we keep a large variety of fishes.

Come to a meeting! Learn about fish and make friends with fellow hobbyists.

Happy Birthday to the
Northwest Arkansas Aquarium Society!

The club’s first official meeting was held on April 29th, 2007. We are now nine years young! We’ve grown a lot in those few years and hope to grow and become even more successful in the future. Happy birthday to NWAAS! Happy birthday to NWAAS!...

Kudos to Michael Gaines (sumpnfishy), Denny Rogers (dennysfishroom), and Corey Mohrhauser (sskruzer), who have been active with the club since the very beginning!

  • This Month’s Meeting
  • Do-It-Yourself Tips Roundtable Discussion

    We’re doing something a little different at our May meeting. Instead of having a speaker with a presentation, we will be having a “do-it-yourself tips” roundtable discussion. Members will be offering show-and-tell descriptions of simple gadgets and contraptions they have devised to make their hobby easier and less expensive.

    Come to listen in or come to participate!
    All attendees are encouraged to bring do-it-yourself tips or projects
    of their own for discussion.

    Saturday, May 14th, 7:00 PM

    Come at 6:30 PM to meet with other hobbyists!
    Program begins at 7:00 PM.

  • Amazon Leaf Fish (Monocirrhus polyacanthus)

    Amazon Leaf Fish

    Vital Statistics




    Origin: Amazon Basin, Peru, Brazil, Bolivia, Columbi, Venezuela

    Size: 3.5 inches total length

    Temperament: timid, but predatory

    Sociability: not safe with smaller fishes; more than one may be kept together

    Breeding: lays eggs on underside of large leaves; male guards eggs

    Sexing: females have more rounded belly in breeding condition

    Diet: carnivorous, live foods are required

    Water Chemistry: pH 5.0–6.0; dH 5–8

    Temperature: 72–78°F


    That which looks like a leaf isn't always so! The Amazon leaf fish is a near perfect mimic of a dead leaf, complete with serrated leaf edges and a stem at one end. Color varies greatly according to mood and background, ranging from light tan to rust to nearly black. Often the fish displays a pattern that resembles leaf veins.

    The fish is an ambush predator that hovers near the leaf litter on the bottom. The closed mouth of a leaf fish gives no hint of its size when fully opened! If prey wanders too close, the large jaws of the leaf fish hinge open, and the voluminous mouth unfolds and telescopes forward in a snap to vacuuum in the unsuspecting prey.

    Even small fishes that don't wander too closely are in danger. The pectoral fins of the leaf fish are completely transparent, allowing it to swim slowly and imperceptibly closer—like a drifting leaf—until the prey is within range.
