yeah, the ideal gar for the home aquaria, and also if you are looking for something on the rarer side of the spectrum, is the tropical gar, Atractosteus tropicus. they don't get terribly large in captivity and are extremely hardy, not to mention they have highly variable but impressive patterns.
i believe mike of H20 Custom Aquatics (one of the vendors on this site) may still have a few, i would suggest contacting him if he ships internationally, otherwise look up that species in areas closer to you.--
