Besides the parasites on wild snails, you still need to be cautious of the types of snails you add to your tank. You can even find you have snails, which turn out to be uninvited guests. In most cases, these join the nuisance brigade.

One snail in your tank will never cause too many issues. However, the uninvited never like to be alone, and before you know it, there are others.

  • Snails can eat aquarium plants and may harm fish if they are weak from illness (disease or parasites)
  • Snails which die will release ammonia into the tank water

How Can Snails Benefit My Aquarium?

If you add snails to your tank, then these are the types, which often work out the beneficial ones. Here are the ways these snails can bring benefits to your tank.

  • Snails will eat dead and decaying plant matter. This prevents the release of ammonia
  • If you are breeding your fish, freshwater snails avoid eating fish eggs
  • Many snails types like burrowing, this means they will aerate your substrate, which helps prevent a toxic element buildup

Will Freshwater Snails Hurt My Fish?

Physically, a snail will never harm a fish. Unless it is sick already, as we have seen, they are too slow to do anything drastic.

The issues come from possible parasites, however, the main one being overpopulation. Once the population grows, we have seen there will be an imbalance, but they can begin to devour everything.

Here are three snails you do not want in your aquariums:

Pond Snails: You find these in outdoor ponds, and you can find them in your tank if you purchase some live plants. The issue here is they sneak in while attached to leaves. The other problem is because they are hermaphrodites; they breed on their own, and don’t require a mate of the opposite sex.

They can reproduce without mates, so the population can increase without you knowing. At this point, they will eat all your plants and anything else they can find.

Rabbit Snails: Rabbit snails add no benefits and produce more waste than they clean. They are quick reproducers in freshwater tanks, so you can find yourself overrun.

Ramshorn Snails: They do look good with their lovely colors and appearance. Aside from that, there is little reason to have these. They eat fish food as much as algae and you can end up feeding your fish more often. Finally, if you have these, they are almost impossible to get rid of from your tank.

  • Trumpet Snails: Algae doesn’t stand a chance with the Trumpet Snail. They are algae eating machines, and besides, they aerate the substrate through burrowing. This dislodges any buildup of anaerobic gasses, which can accumulate.
  • Assassin Snails: While they do little for the cleanliness of your tank by eating algae, the Assassin Snail can control the population of other snails. One thing that makes this different is they require a mate to reproduce; thus, they won’t overpower your tank with their population.
  • Nerite Snails: Being one of the most popular snails to have in your tank. Nerite Snails love to search out algae to eat. They find this on hard surfaces like the tank walls and substrate. The primary benefit of these is they don’t reproduce in freshwater aquariums, so controlling their population is easy.
  • Mystery Snails: A Mystery Snail is a great addition because they are another that will clean the bottom of your tank of uneaten food and algae. If there is a downside, it is they are experts in escaping from fish tanks, so you do need a lid on your tank.
