Top 7 tankmates for your Corydoras

Corydoras are a bit of an interesting fish because normally you are not going to suggest tank mates for Corydoras but instead, you are going to use them as tankmates for other fishes.

Corydoras are really good community fish which is kept with a bunch of different types of fish because they stay relatively small, they are also very peaceful and not aggressive at all plus they stay at the bottom of the aquarium. So, they are one of the most commonly found fish in the aquarium.


This contains almost all types of Rainbowfish except for some which get huge. There are amazing little fish which comes in a huge variety of color. They come from the Australian region, they are very peaceful and schooling fish.

When looking for compatibility with the Corydoras, you should go more towards the dwarf neon Rainbowfish, Boseman's Rainbowfish, the Turquoise Rainbowfish; there are tons of variations you can choose from.

Compatibility with Corydoras

  • The best thing about these fish is that they stay at the top of the aquarium, so they are not going to go in the way of Corydoras.
  • They both eat about the same food, so you can chunk flakes in your aquarium and your rainbows will eat it, and then the food is gonna float at the bottom of the aquarium where the Corydoras can have it.
  • One more good thing is that they have relatively similar water conditions, these guys like a bit more of harder water. Corydoras on the other hand like soft water but they can kind of bear with that 7.5 pH range and if you keep both of them in the same water condition you are really going to have a lot of success with these guys.

These are really great fish, you can also easily breed them just chuck a spawning mop in there, and can make a tone of babies.


The cons of having these fish are that they can be relatively expensive and also they are not a super good beginner fish. They are kind of a more intermediate style of fish, beginners should try other fish before this because they are prone to few fluctuations in the water and some of the beginner mistakes that you are destined to make as you start with the hobby.


This too includes all types of Angels. They are an excellent fish to keep because they look absolutely beautiful and secondly they are easy to breed; there is literally no other fish that looks like the Angelfish.

Compatibility with Corydoras

  • These fishes have a very good relationship with the Corydoras.
  • The Corydoras obviously are going to stay at the bottom and angelfish will be staying at the top. They are not gonna really have much to with each other.
  • When you feed you Angelfish they are going to crowd the food which will force the food to sink to the Corydoras and they can clean it up, and they just really work well together.

There are a bunch of different types of Angelfish that you can get. They are not the easiest fish to bread but they can be relatively easy if you get a pair. 

Overall they are very personable fish and they are really good for beginners because they are super hardy fish.


Both the Corys and the Bristelnose work together as a cleanup crew. These guys are notoriously known for going on the surfaces of things in the aquarium and cleaning up like the dust-green algae.
