Behaviour & Temperament
American Grass Shrimp is a peaceful species (1/10), while Apple Snail is peaceful (0/10). This modest difference means American Grass Shrimp may occasionally assert dominance over Apple Snail.
American Grass Shrimp and Apple Snail both frequent the Bottom (Substrate) and Middle (Open Water) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.
Worth noting: American Grass Shrimp is a known jumper, so a tight-fitting lid is essential.
Water Parameters
The safe temperature window for both species falls between 20°C and 28°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.
Both fish can tolerate a pH between 7.2 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 8–15 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup
To house American Grass Shrimp and Apple Snail together, plan for an aquarium of at least 150 litres with a minimum length of 90 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.
Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.
Specific environmental needs for this combination include: Plants - Densely covered, Leaf Litter/Blackwater, Established Algae (Otocinclus), Shells (Breeding/Hiding). Meeting these requirements will help both species thrive.
Note a potential conflict in setup requirements: Apple Snail is a plant destroyer, which conflicts with American Grass Shrimp's requirement for live plants. Compromise where possible or prioritise the more critical need.
Both species do well with moderate (standard) water movement, so a standard filtration setup rated for the tank volume should suffice.
