Nutrition - Mainly plant-matter, in the aquarium will eat also uneaten fish foods and meaty foods such as

dead fish corpses. Needs Calcium additions to its diet!

Behavior – calm and harmless.

Maintenance and care - This species requires an aquarium with slow water flow and good biological

filtration, due to its tendency to pollute water quickly. As this snail is fast growing, it needs calcium

rich water, so it can grow with a healthy shell- the calcium is used as calcium-carbonate to create the

shell, lack of calcium will cause the shell to be thinner and more susceptible to breaking and eventually,

the snail will die.

Water Parameters – temperature: 16C-30C, PH: 6 – 8.5.

Breeding – very easy to breed. Laid below the water surface. The Marisa snails differ from many other

Ampullarid snails by the fact that they deposit their eggs in a gel-like substance in the water

(other Ampullarid snails deposit their eggs above water surface).
