Species often confused with {name}
Red Ramshorn Snail
Planorbella duryi (often misidentified as Planorbarius corneus in the aquarium trade)
Key differences: While often sold as 'Red Ramshorn', Planorbella duryi (and other Planorbella species) are generally smaller (typically up to 20 mm), have a more pronounced reddish coloration (often genetically selected for), and their shell coiling can be slightly different, though still planospiral. True Planorbarius corneus is larger and typically a darker brown/red.
Trumpet Snail
Melanoides tuberculata
Key differences: Trumpet snails have a tall, conical, spiraled shell, completely different from the flat, discoidal shell of Planorbarius corneus.
Bladder Snail
Physa acuta
Key differences: Bladder snails have a sinistral (left-handed opening) shell that is typically smaller and more elongated/oval than the planospiral shell of Planorbarius corneus.
