Do Angelfish Eat Rocks?

Angelfish are indeed beautiful creatures as they come in various colors and have intricate markings on their bodies that make them stand out among other fish.

However, when it comes to aggression, Angelfish are considered semi-aggressive fish that may nip your rock or even your fingers!

In this article, We’ll answer all of your questions about angels’ aggressive behavior, from why they nip rocks to whether their nips are dangerous to your fingers!

Why Do My Angelfish Eat Rocks?

Angelfish are omnivorous. They need a healthy diet that contains meat and vegetable sources.

So, If you do not provide them with a balanced diet, they may start to look for other food sources, including rocks.

Don’t get me wrong, I don’t mean they will actually eat the rocks, what I mean is they will nip on them.

Angelfish are known as “nature’s janitors,” meaning they continuously nip through the substrate and décor of an aquarium, looking for uneaten food, leftover fish poop, and anything else they can find. This is why you may find your angelfish pecking at the rocks in your aquarium.

Is It Safe for Angelfish to Eat Rocks

It is not healthy for your fish to eat rocks and can lead to problems such as intestinal blockages. That’s why it’s important to keep a close eye on your angelfish to ensure that they’re not eating any rocks or other items in the aquarium.

New rocks or décor should be boiled or soaked in water for a few hours before adding them to your aquarium. This will help ensure that they’re not carrying any uninvited hitchhikers into your tank!

Do Angelfish Have Teeth?

Yes, angelfish have teeth, but they are not found in their jaw. Rather, the teeth are located in the throat.

Do Angelfish Bite People?

Yes, angelfish can bite humans. They won’t necessarily consume you, but they might nip at you if provoked.

Anyone who comes into contact with an angelfish will be bitten. They will not show you special favor because you are their owner.

Yes, you can teach angelfish to recognize you. However, when your fingers are in their water, they won’t be able to tell which ones are yours.

When angelfish bite humans, the most common scenario is when they are feeding them. This happens because many fish owners prefer to feed their fish with their hands instead of poring the food into their tanks. 

Also, if they have eggs and fry in the tank, don’t be shocked if your angels nip your hand.

This is particularly true whenever you get too close to their breeding site. It may have something to do with their territorial behavior.

If they see you as a potential threat to their children, they will not hesitate to attack you.

It’s not a big deal. The occurrence is more startling than painful in most situations. So don’t be concerned about it. Your angels’ teeth and jaws aren’t strong enough to inflict any significant damage.

Will Angelfish Bite Other Fish?

Angelfish are semi-aggressive species, and they can bite other fish. Various factors can encourage this aggressive behavior, including:

1. Level of the Aquarium

The majority of an angelfish’s existence is spent swimming near the water’s surface in the top layer of the water column.

Tankmates from the same level may be viewed as competition for food, resulting in aggression.

This is why you should consider carefully before adding fish that occupy the same level as your angels in the aquarium.

2. Water Parameters Difference

The pH range for angelfish is 6.5 to 8.0, with nitrates and ammonia concentrations of 0 being optimal. Providing them with the water condition they need is crucial not to stress them out and limit their aggressive behavior.

3. Size Does Matter

When fully grown, an adult angelfish may reach six inches and a height of eight inches.

It’s not only the room that might be problematic here. As we mentioned before, angelfish isn’t a peaceful fish, so some rasboras and very small tetras will be food for her.

On the other hand, if you put a very large fish with your angels, they will bully and attack it, so you must put your angels with suitable tankmates.

4. Levels of Aggression

Putting other aggressive species in the same tank as your angelfish is a nightmare because it will trigger aggressive behavior in your angelfish and turn your tank into a battleground.

Therefore, it’s important not to choose aggressive species for your angels.

Last Words

In general, angelfish can be quite dangerous to their tankmates and rocks in your aquarium, so you have to keep an eye on them.
