Can Chocolate Gourami and Mystery Snail Live Together?

Chocolate Gourami is a peaceful species (2/10), while Mystery Snail is peaceful (0/10). This modest difference means Chocolate Gourami may occasionally assert dominance over Mystery Snail.

Chocolate Gourami and Mystery Snail both frequent the Top (Surface), Middle (Open Water), and 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: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Worth noting: Mystery Snail is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 25°C and 28°C. Aim for the midpoint of this range (around 26.5°C) for optimal comfort.

The pH requirements of Chocolate Gourami (4–6.5) and Mystery Snail (7–8.5) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Chocolate Gourami needs 0–5 dGH while Mystery Snail requires 8–20 dGH.

To house Chocolate Gourami and Mystery Snail together, plan for an aquarium of at least 55 litres with a minimum length of 60 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: Leaf Litter/Blackwater, Plants - Densely covered, Plants - Floating, Driftwood (Digestion/Hiding), Established Algae (Otocinclus). 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.
