The MASI Challenge
We started the MASI Challenge in 2004 to encourage our local members and those of other aquarium clubs around the US to raise funds for and support education and charitable programs in the aquatic field. This was started with a donation to the Vern Parrish Fund of the American Livebearer Association (ALA), which awards annual grants to graduate students working with and studying livebearing fishes. A public challenge was made to the entire organization (ALA) to help support the Vern Parrish Fund which resulted in quadrupling our startup Challenge donation to the VPF. That year they were short of funds to make a single grant, with our donation and the subsequent response of other clubs, they were able to make two grants. We have run the MASI Challenge as an annual event ever since.

MASI was officially incorporated as a charitable and educational organization promoting the aquarium hobby in 1959, but was active for several years before as an informal group of friends who met in each other’s homes on a monthly basis
Several of our original founders were WWII and Korean War vets who installed and maintained aquaria in the “day rooms” of various veteran’s hospitals and rehab facilities free of charge – this charitable work carried over into the mission of MASI to this day
Some examples of our many charitable and educational works in furtherance of our above stated bylaws since the 1950s
