Behaviour & Temperament
Alligator Gar is a semi-aggressive species (7/10), while Orange Delight Shrimp is peaceful (0/10). This notable difference means Alligator Gar may occasionally assert dominance over Orange Delight Shrimp.
Large aggression gap (7 points) between Alligator Gar and Orange Delight Shrimp increases stress risk for the more peaceful fish.
In terms of spatial distribution, Alligator Gar prefers the Top (Surface) and Middle (Open Water) zones, whereas Orange Delight Shrimp occupies the Bottom (Substrate) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.
There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) trait of the other — piscivorous fish will prey on nano-sized tank mates..
Worth noting: Alligator Gar is a known jumper, so a tight-fitting lid is essential.
Water Parameters
The safe temperature window for both species falls between 26°C and 29°C. Aim for the midpoint of this range (around 27.5°C) for optimal comfort.
Both fish can tolerate a pH between 7.5 and 8. Maintaining a stable value within this band is more important than hitting an exact number.
For general hardness, the shared comfort zone is 8–8 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house Alligator Gar and Orange Delight Shrimp together, plan for an aquarium of at least 8000 litres with a minimum length of 400 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.
Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.
Specific environmental needs for this combination include: Smooth Gravel (Sensitive Barbels), Sand (Sifters), Established Algae (Otocinclus). Meeting these requirements will help both species thrive.
Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.
