- Giant Brown Apple Snail, Canas Snail, Channeled Apple Snail
- Native to Argentina, Paraguay, Bolivia, Uruguay, and Brazil. Non-native populations established in Southeast Asia, and the U.S. It has an invasive tendency compared to the related Spike-Topped Apple Snail, and the Golden Apple Snail because while the two related species are reluctant to leave the water surface, this species eagerly exits the water, as demonstrated in the home aquarium, where it has been known to make an escape from uncovered aquariums.
- Similar to the method used for the Apple Snail species Pomacea bridgesii Difficult, these are NOT hermaphroditic snails. Female grows faster than the male at first. In male snails the shell opening tends to be larger and rounder, due to the penial complex (easier to see in large numbers). It is easier to estimate the sex by looking inside the shell opening to see the penial complex. This will not be visible in females. Just take the snail out of the water and keep it upside down. The snail will stretch its foot out (as if it is trying to flip over). Once it has extended out to a point, if you look to the right of the mantle, you should see a large penis sheath in front of the gills. In a female snail the sheath will be absent.
- A peaceful large snail, will not bother tank inhabitants. However, do not keep with aggressive fish such as Loaches or Puffer Fish.
- Will eat aquatic plants, so do not keep in a planted tank.
- How often to feed, etc.
- In the home aquarium: 7+pH, high levels of calcium, 1" clearance at the top of the tank ( If trying to breed.), Any traces of copper or copper compounds will kill them.
- Peaceful, will not attack any tank-mates other than plants, usually only if food is scarce. Will willingly exit the water.
- This is one of the largest freshwater snails in the world. It's shell is smooth, round and relatively heavy. It has 5-6 whorls and is coloured from yellow, brown or green. The wild form has dark spiral bands. Pomacea canaliculata group: indented sutures, less than 90°angle.
This shell is more globose (rounder) than the Pomacea bridgesii shell.
