Atractosteus spatulaAlligator Gar
Lepisosteidae · Lacepède, 1803
This is one of the largest freshwater fish species in the world, and clearly shouldn't be considered a home aquarium subject at all given its eventual size and the fact it can live for well in excess of 50 years. We include it here only because some public aquaria are able to maintain it long-term. Unfortunately, juveniles are seen for sale quite regularly in the aquari...

Ctenopharyngodon idellaGrass Carp
Cyprinidae · Valenciennes, 1844
Despite being a wholly unsuitable aquarium subject, C. idella is often traded as such, with an albino form having been developed specifically for the ornamental market. Individuals which have outgrown their aquarium or pond should never be released into natural waters, either, since this species has proven capable of causing serious environmental damage under a wide range of climatic conditions.

Lepisosteus oculatusSpotted Gar
Lepisosteidae · Winchell, 1864
Known from Great Lakes Erie and Michigan with distribution extending south through the Mississippi River basin to the Gulf of Mexico drainages where it's said to occur between the lower Apalachicola River in Florida and the Nueces River in Texas. It may also be found in the Rio Grande which forms the border between Mexico and the United States further south where records include Falcon International Reservoir, for example.
