? What Is a King Koopa Nerite Snail?

The King Koopa Nerite Snail, also known as the Horned Nerite Snail (Clithon corona), gets its nickname from the small spikes or “horns” protruding from its shell, giving it an armored, prehistoric appearance. These snails usually have dark olive to golden shells with black stripes or markings — every individual has a slightly different pattern.

Though they look fierce, they're totally peaceful, algae-eating powerhouses ideal for tanks of all sizes.

? Why They're Popular

✅ 1. Incredible Algae Control

Koopa Nerites eat:

• Soft green algae

• Biofilm

• Diatoms (especially helpful in new tanks)

They’re efficient, non-destructive grazers that clean glass, rocks, driftwood, and even plant leaves — without eating the plants themselves.

✅ 2. No Overbreeding in Freshwater

Nerites require brackish water to reproduce, so in freshwater aquariums, they will not breed, even if eggs are laid. This makes them ideal for aquarists who want utility without population problems.

✅ 3. Tough and Eye-Catching

Their spiky, armored appearance sets them apart from typical aquarium snails. They’re tiny tanks — slow-moving but sturdy and stylish.

⚠️ Things to Watch For

• Wandering Snails: Koopa Nerites may climb out of tanks if water levels are high and there’s no lid. Always keep a lid on to prevent escapes.

• Egg Spots: Females may lay tiny white egg capsules on hard surfaces. These won’t hatch in freshwater but can be visually distracting for some aquarists.

• Copper Sensitivity: Avoid copper-based meds and fertilizers — they're deadly to all snails.
