Can Assassin Snail and Sparkling Gourami Live Together?
Keeping Assassin Snail and Sparkling Gourami together is possible but requires caution due to potential behavioral clashes. Provide a spacious tank of at least 46 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.
At a Glance
Behaviour & Temperament
Assassin Snail is a peaceful species (2/10), while Sparkling Gourami is generally mild-mannered (3/10). This modest difference means Sparkling Gourami may occasionally assert dominance over Assassin Snail.
Assassin Snail and Sparkling Gourami both frequent the Bottom (Substrate) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.
Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.
Water Parameters
The safe temperature window for both species falls between 22°C and 28°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.
Both fish can tolerate a pH between 7 and 7.5. 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 Assassin Snail and Sparkling Gourami together, plan for an aquarium of at least 46 litres with a minimum length of 45 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.
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: Sand (Sifters), Plants - Densely covered, Plants - Floating, Leaf Litter/Blackwater. Meeting these requirements will help both species thrive.
Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.
Diet & Feeding
Feeding time deserves special attention with this pairing. Sparkling Gourami is a known shrimp eater and may prey on small invertebrates or nano fish like Assassin Snail.
