A prehistoric, heavily armored ambush predator native to the southeastern United States. They possess an elongated, torpedo-like body and a beak filled with sharp teeth. As an apex predator, they will consume any tank mate that fits in their mouths, but are generally peaceful toward fish too large to eat. They require massive aquariums and a secure, weighted lid due to their powerful jumping capability.

Available Varieties
Each variety inherits the species defaults above. Only differences are highlighted.
Adult (Standard)
The fully grown adult form. Requires a massive custom aquarium (minimum 8 feet long) to allow this rigid-bodied fish to turn around safely. Must be kept with similarly sized, robust tank mates.
Differs in 1 trait from base species
Also known as: Monster Fish, Adult Gar
Juvenile (Grow-out)
Juvenile Gars are commonly sold around 4-6 inches. While they can temporarily be housed in smaller aquariums, their explosive growth rate means they will require a permanent monster-sized enclosure within their first year.

Florida Gar Care Guide Summary
The Florida Gar, scientifically known as Lepisosteus platyrhincus, belongs to the Oddballs family group. Adults reach a maximum size of approximately 80 cm and have a fusiform body shape with a fast growth rate. Classified as aggressive, this species primarily occupies the surface and mid-level zones of the aquarium and produces a extreme level of biological waste.
To thrive, the Florida Gar requires a brackish tolerant aquarium with a minimum volume of 1100 litres and a tank length of at least 240 cm. Water temperature should be maintained between 15°C and 30°C, with a pH range of 6–8 and a general hardness of 8–20 dGH. A moderate water flow is preferred. An aquarium test kit can help you monitor these values.
Due to its specialist needs, the Florida Gar is best suited for fishkeepers who can provide a carefully planned setup. This species is available in 2 varieties: Adult (Standard) and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.
Florida Gar Habitat Setup
When setting up an aquarium for the Florida Gar, a moderate water flow best suits their natural preferences. Because this species occupies the surface and mid-level zones, the aquarium layout should prioritise adequate surface area with floating cover to make them feel secure near the waterline and open swimming space in the centre of the tank for free movement. Useful additions include floating plants to diffuse overhead light and create shaded areas. Keepers should note that a tight-fitting lid is essential, as this species is a known jumper.
Florida Gar Compatibility Notes
Classified as aggressive, the Florida Gar is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, any fish small enough to fit in its mouth will likely be eaten and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the surface and mid-level zones can help reduce competition and territorial overlap.

Clown Knifefish
Chitala ornata
A massive, nocturnal predator native to Southeast Asia, widely known for the distinct row of ocellated spots above its anal fin. While sold as small silvery cute juveniles, they grow incredibly fast into nearly 1-meter giants that require immense aquariums. They are obligate carnivores and will eat any fish small enough to fit in their large mouths. They are shy during the day and require large hiding tubes or caves.
Fahaka Puffer
Tetraodon lineatus
A massive, highly intelligent, and extremely aggressive freshwater pufferfish native to the Nile, Senegal, and Niger rivers. Often referred to as 'water dogs' due to their owner recognition and begging behavior. They are strictly solitary pets that will relentlessly attack and kill any tank mates. They require a diet of hard-shelled invertebrates to keep their ever-growing teeth trimmed.
Florida Flagfish
Jordanella floridae
A robust, deep-bodied killifish native to Florida. Unlike most killifish, they are primarily herbivores and are renowned for their ability to eat Hair Algae and sometimes Black Beard Algae. They are sub-tropical and thrive in unheated aquariums. They can be fin-nippers, especially if underfed or kept with long-finned tank mates.
Indonesian Datnoid (Tiger Fish)
Datnioides microlepis
A massive, deep-bodied ambush predator highly prized by monster fish keepers for its striking black and gold 'tiger' stripes. Native to the freshwater rivers of Southeast Asia, they possess huge mouths and will consume any fish small enough to fit. They are notoriously shy when young but grow into bold, impressive centerpieces. Due to intense conspecific aggression, they should be kept entirely solitary or in groups of 4 or more to disperse bullying.
Jaguar Cichlid
Parachromis managuensis
A massive, apex predator from Central America known for its striking jaguar-like pattern and extreme aggression. Jaguars are highly intelligent, wet-pet fish but require enormous aquariums and heavy filtration. They will consume any fish that fits in their mouth and aggressively rearrange their environment.
Bucktooth Tetra (Exodon)
Exodon paradoxus
The Bucktooth Tetra is a highly active, predatory shoaling fish infamous for its scale-eating (lepidophagous) behavior. They are extremely aggressive and will strip the scales, fins, and even eyes off almost any tankmate. They must be kept in a species-only tank in large groups (12+) to disperse their intense conspecific aggression; otherwise, they will systematically kill each other.
