Will kribensis eat or attack a nerite snail?

No. Nerite snails are well-protected by their hard shell and kribensis have no interest in bothering them. Kribensis focus on their own territory and leave nerite snails alone entirely.

Will kribensis eat nerite snail eggs?

No. Nerite snail eggs are laid above the waterline on hard surfaces and are completely out of reach for kribensis.

What water conditions do this combination need?

Set the tank to 77-79F and pH 7.0-7.5. Nerite snails need calcium for shell health, so ensure adequate hardness. Kribensis adapt to a range of conditions, so meeting the snail standard covers both.

How many nerite snails can I keep with kribensis?

One nerite snail per 5 gallons works well. A 20-gallon tank supports 3-4 nerite snails easily. They produce minimal bioload and kribensis pay them no attention.

Can Kribensis Live With Nerite Snail?

By Alex WalshLast reviewed Apr 18, 2026

Yes

Yes, kribensis and nerite snails coexist well in a 20-gallon tank, with both species preferring similar alkaline water conditions.

Why

Nerite snails grow to 1 inch and have a hard shell that kribensis at 4 inches cannot break or eat.
Temperature overlap spans 75-80F, with kribensis preferring 78F and nerite snails preferring 76F.
pH ranges overlap from 7.0-7.5, which suits both species comfortably and supports nerite shell health.
Kribensis are bottom-dwelling cichlids that focus on their cave territory while nerite snails graze on glass and surfaces.
Kribensis ignore nerite snails because the hard shell and slow movement do not trigger prey drive.

What could go wrong

Kribensis occasionally nudge nerite snails out of the way near their cave, but the armored snail is unharmed.
