Do Fish Eat Slugs?
Yes, in general, fish eat slugs. However, since these two species have various types, this source of protein is not always a favorite treat for some specific types of fish. Panfish or loach species will be glad to have snails as their food, while the slug slime is a deterrent for the minnow to enjoy.
Most of the time, slugs are safe for fish to consume since are not poisonous. Just one thing to remember is that the mucus (the thicker or more fibrous one) produced when they’re frightened may make them unappetizing or difficult for fish to digest.
What Fish Eat Slugs?
The first candidate for our freshwater pet that eats snails is the Yoyo loach. They consume slugs and are a good solution to control the slug population. Plus, their small size makes them suitable for the aquarium.

Goldfish can eat slug eggs. However, since it feeds on other plant and animal matter, having it to control the slug overpopulation is not a good idea. Just use it when you have no other option.
Dwarf Chain Loach

Bala Shark is not a typical snail eater as its favorite target is not live food. However, its giant mouth can stomach large prey items, including slug eggs.
How Do Slugs Get Into Your Aquarium?
You accidentally put them there is the only way this pest can appear in your aquarium. While transferring gravel cultures or placing plants inside the tank, you may unintentionally leave some slug eggs as they hitchhike on those decorations.
Some snails can live long and are ready to replicate on any new surfaces, even if you wash the gravel or decorations carefully before reusing. Malaysian Trumpet snails are an example. They can attach to the stone, rocks, driftwood, plants, etc., and start their new life in a new home without you knowing.

Plus, it’s not easy to see the snail eggs as some are transparent and hide under the leaves. Take red ramshorns and pond snails as examples. The fine-leaved plants are the favorite places for these small juveniles to get away from your eyesight.
Control Slug Population Options
Not all snails are bad, but when they cover your tank walls and decorations too much, it signals some control options should be applied. There are two safe, natural methods to use.
The first one is adding some of the eating snail fish listed above to your aquarium. These new crews will enjoy their feeding party without harming other tank members.

The second way is manually removing the slugs, yet not plucking them out one by one with your bare hands. All you need to do is put a piece of lettuce in hot water and then leave it in your aquarium for one night.
The decaying plant attracts the snails. The next day, you will see lots of these species gather there. Throw the lettuce leaves, and your mission is completed.
Remember not to rush for some chemical solution at first since it can do more harm than good. It may help eliminate the snails but also kills other invertebrates. Plus, good bacteria can vanish, resulting in an unwanted drop in water quality.
Do fish eat slugs? Now you know slugs are suitable for most fish. This type of pest can be both good and bad. If you see a sign of infestation from them, add some fish specialized as the snail population controller or regulator into your aquarium to address the problem.
