Tank Setup
To house Clown Loach and Malaysian Trumpet Snail (MTS) together, plan for an aquarium of at least 500 litres with a minimum length of 150 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: Sand (Sifters), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding), Soil / Nutrient Rich. Meeting these requirements will help both species thrive.
Note a potential conflict in setup requirements: Clown Loach requires Sand (Sifters), while Malaysian Trumpet Snail (MTS) requires Soil / Nutrient Rich. These substrate types may be difficult to provide simultaneously. Clown Loach requires Smooth Gravel (Sensitive Barbels), while Malaysian Trumpet Snail (MTS) requires Soil / Nutrient Rich. These substrate types may be difficult to provide simultaneously. 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.
Suitable Tank Sizes
Standard aquarium sizes large enough for both Clown Loach and Malaysian Trumpet Snail (MTS).
