How Many Turbo Snails Per Gallon?

If you’re buying them for algae control, it’s best to keep 1 Turbo snail per 5-10 gallons. As mentioned, Turbo snails are voracious eaters, they eat algae or vegetable wafers. Obviously, it will depend on the conditions of the tank and the number of algae present in the tank.

If your current amount of Turbo snails cannot control the rapid growth of algae, you can keep 1 Turbo snail every 1-3 gallons. But personally, I think that’s a bit too much. Be careful when deciding to add too many Turbo snails because their appetite is very large. They can starve if they don’t have enough food.

Keeping Mexican Turbo Snail

I have found that it is both very easy and very difficult to keep Mexican Turbo snails at the same time. In order to provide them with the ideal environment, you do have to take into consideration some specific requirements. A Mexican turbo snail cannot survive well in a saltwater aquarium with high temperatures since these creatures are not adapted to high temperatures. Moreover, they are also incapable of withstanding high levels of poor husbandry due to their narrow tolerance range.

Tank size

It is important that Turbo snails are kept in a large, established tank with enough space and water volume to support its needs. These snails require a minimum tank size of 10 gallons (40 liters). It is always better to have a large tank than a small one.

Water Parameters

It is recommended that the water in the tank where Turbo snails will reside is between 20 and 26°C (68 and 80 °F), although around 70 to 73°C (21 and 23 degrees Celsius) is an ideal temperature. Alkalinity levels of 8 to 12 pH value must be between 8 and 8.4 for optimum performance. and specific gravity that is between 1.023 and 1.025.

Substrate and Decorations

If you want to use either sand or small gravel as a substrate, you can use either. Mexican Turbo snails prefer living in intertidal sandy-bottom substrates in their natural environment in order to survive. Sand, then, is one of the best substrates suitable for these organisms. Additionally, these snails are also very good at helping the substrate to aerate.

It is recommended that you include a lot of live rock in the tank for the Turbo snails to graze on and also so they could use them as hiding places. 

Filtration and Lighting

There is no need to use fancy filtration and lighting for them. If you are just interested in getting a regular LED aquarium light, you can just buy one. 

However, Turbo snails are not very hardy and quite sensitive to changing habitats. It is therefore extremely important to acclimatize them before introducing them to your tank.
