Best tank mates (on file)

Merged from conservative safest and best with fields — de-duplicated by species.

Amano Shrimp Pair check
The Malaysian Trumpet Snail profile lists Amano Shrimp as both safe and a recommended pairing. Amano Shrimp grows bigger than Malaysian Trumpet Snail (5cm vs 2.5cm). Stock the Malaysian Trumpet Snail group large enough to outnumber the Amano Shrimp, or the smaller fish ends up bullied or off food.
Cherry Shrimp Pair check
The Malaysian Trumpet Snail profile lists Cherry Shrimp as both safe and a recommended pairing. Cherry Shrimp schools in groups of 10 or more, so plan room for the whole group rather than one fish.
Corydoras Catfish Pair check
The Malaysian Trumpet Snail profile lists Corydoras Catfish as both safe and a recommended pairing. Corydoras Catfish schools in groups of 6 or more, so plan room for the whole group rather than one fish. Corydoras Catfish grows bigger than Malaysian Trumpet Snail (6cm vs 2.5cm). Stock the Malaysian Trumpet Snail group large enough to outnumber the Corydoras Catfish, or the smaller fish ends up bullied or off food.
Harlequin Rasbora Pair check
The Malaysian Trumpet Snail profile lists Harlequin Rasbora as both safe and a recommended pairing. Harlequin Rasbora schools in groups of 6 or more, so plan room for the whole group rather than one fish. Harlequin Rasbora grows bigger than Malaysian Trumpet Snail (5cm vs 2.5cm). Stock the Malaysian Trumpet Snail group large enough to outnumber the Harlequin Rasbora, or the smaller fish ends up bullied or off food. Harlequin Rasbora swims in the middle zone while Malaysian Trumpet Snail stays in the bottom, so the two will not crowd the same water column.
Neon Tetra Pair check
The Malaysian Trumpet Snail profile lists Neon Tetra as both safe and a recommended pairing. Neon Tetra schools in groups of 6 or more, so plan room for the whole group rather than one fish. Water parameters barely overlap between the two, so check the temperature and pH ranges on both profiles before stocking. Neon Tetra swims in the middle zone while Malaysian Trumpet Snail stays in the bottom, so the two will not crowd the same water column.

Risky or situational

Marked risky or situational on the profile. Tank length and group size change the outcome more than a temperament label does.

Fish to avoid with Malaysian Trumpet Snail

From the unsafe list — predation, aggression, or space rules on this profile.

Pea Puffer See why (pair)
