Will Snails Eat Fish Eggs? Lets find out

Snails are one of the best-known tank cleaners. Whenever aquarists talk about aquariums’ health and wellness, the first tank mate that comes to mind is snails. Moreover, snails add beauty and enthusiasm to fish tanks. But a query always pops up in our imagination while keeping snails and our favorite fish: “Will Snails Eat Fish Eggs?”

Snails can eat fish eggs. If they get the opportunity or their size is big enough, they definitely eat fish eggs. However, “Can snails eat fish eggs” purely depends on the specific species of snails. Some snail species love to eat eggs, while others don’t pay attention to fish eggs.

Do you know various snails are optimistic feeders, and they don’t care about the harmony of fish tanks? They ruthlessly eat anything that comes their way, whether a fish egg or any other snail. I understand it sounds scary when considering keeping snails with your fish as a beginner. However, I hope you’ll feel better at the end of this topic.

Let’s jump into the insights!

Will snails eat fish eggs?

Yes, snails eat fish eggs. These little darlings look cute, but some love to gobble up fish eggs. They eat not just fish eggs but eggs of other snails and their own eggs. If you put hard-boiled chicken eggs in the fish tank, these snails will eat them.

It’s just like “anything is a fair game” for some snails in terms of their dinners and lunches. They even eat many fish species. Just imagine how dangerous some snails are! On the other hand, many snail species ignore fish eggs and only scavenge on algae and fish leftovers.

Important Note:

Bigger Nerite and Apple snails make up a good companion with many friendly fish species in the same tank. If you give them egg yolk, they share their food and do not attack each other.

Many aquarium keepers intentionally offer them protein-packed eggs to meet their nutritional needs. In this case, make sure you are feeding them hard-boiled egg yolk as a hearty snack to both tank mates – fish and snails.

Why do snails eat fish eggs?

Snails have diverse food choices to consume from, and fish eggs are one of them. They eat fish eggs because they are usually soft and easy to consume. Moreover, fish eggs are full of proteins and calcium.

Gelatinous is another essential thing in fish eggs that makes them appealing to snails. Also, fish eggs are easy to digest. Some snails find it easier to survive on nutritionally rich sources than others.

Which snail species eat fish eggs?

There are many snail species that like to eat fish eggs. Here is the list of a few snail species that are commonly known to eat fish eggs regularly and sometimes opportunistically:

  • Bladder Snails: These snail species are relatively smaller in size and commonly found in many fish tanks. However, they do not eat fish eggs regularly. They are known to eat fish eggs accidentally while grazing on other food items on aquarium surfaces.
  • Pond Snails: These snail species are inhabitants of freshwater. According to various scientific studies, pond snails eat fish eggs. They mainly eat them in the wild, but pet pond snails do not eat fish eggs.
  • Ramshorn Snails: These snail species are omnivorous. That’s why ramshorn snails are known to eat eggs of many fish species with other foods, especially tiny organisms.
  • Trumpet Snails: These snail species are primarily called detritivores. Still, they like to eat fish eggs if any egg comes in their way of hunting food items.
  • Assassin Snails: Everyone knows that Assassin snails are popular among aquarists due to their predatory nature. These snail species do not show mercy on other snail species and eat them. Then, how can we expect assassins not to eat fish eggs? They eat!

Here is another important thing that I want to share. All individuals of each of these snail species do not eat fish eggs. This is because every individual has unique eating habits that make them distinct from other species.

Moreover, food availability matters a lot. Sometimes, a few individuals of the above-mentioned snail species do not eat fish eggs if other foods are available for them. Otherwise, they eat fish eggs out of hunger (opportunistically).

  • Caloric energy: The lipids (fats) in fish eggs can provide an additional energy source to snails.
  • Calcium content: Some fish eggs have calcium content in their shells. It is beneficial for the snail’s shell development.
  • Dietary variety: As you know, a diverse diet can help prevent nutritional deficiencies. So, fish eggs change the taste of the tongue of snails.
