The corydoras catfish is only one of the most favorited scavenger fish in the aquarium hobby! The corydoras catfish is an excellent addition to community tanks since it is content with scavenging for scraps. The corydoras catfish is also one of the most peaceful fish you could ever meet as well so you shouldn’t expect much out of these little cuties.
Corydoras Catfish are very cool to keep in your tank with your other tank mates but what about an aquarium with just Corydoras Catfish? Yes, you can have an aquarium with just Corydoras Catfish. In fact, I have seen a tank with 80 Corys at 1 time which is absolutely crazy! But generally, you should try to stick with 3 to 8 Corydoras Catfish in one tank.
Corydoras Catfish are arguably the most common type of freshwater aquarium fish you can own. The Corydoras are apart of the Callichthyidae family. One of the many reasons why these little cuties are a freshwater aquarium favorite is their unique body markings, colorations, and their cute barbels whiskers resembling that of a catfish hense Corydoras Catfish.
The Corydoras catfish are armored with protective bony plates which makes them a bit of a headache for large fish and goldfish as well. Their size makes them a snack for most larger fish since the usual size of the Corys is 2 to 3 inches and they can be as small as an inch.
What Do Corydoras Catfish Eat
Corydoras Catfish use their barbels to help them locate their food. You will see them scavenging moving rocks and debris looking for food. Other than the food, the Barbels are used to help the corys find their way around the aquarium tank. Corydoras Catfish are omnivores by nature hence scavengers but there are quite a few things you can feed them.
Flakes: Corydoras Catfish will eat just about anything that sinks to the bottom so flaked food shouldn’t be any different. Corydoras Catfish are going to primarily enjoy more meat-rich scraps. Even so, the food flakes do have some nice nutrients in them that will benefit the corys and your tank mates.
Food Pellets: The Corydoras Catfish will eat food pellets. If you see them biting them and the pellets do not seem to be going into their mouths it is okay. The Food Pellets are still too hard and will dissolve enough for the Corydoras Catfish to eat them so this is something to not worry about.
Shrimp Pellets: Shrimp Pellets are a good choice food for the Corydoras Catfish since the shrimp pellets are more of a meat-based food source. Shrimp is a favorite food choice for almost every type of fish in the aquarium hobby so being familiar with the shrimp especially brine shrimp is a must!
Brine Shrimp: Brine Shrimp will make almost every type of fish swim fast for a chance to snag these guys for a snack. Brine shrimp are a very high protein source and being as these guys are in a smaller enclosure than their lakes, ponds, and streams they will take the protein to enrich opportunity.
Brine shrimp are easy to raise for your fish but just as easy to purchase as well.
Bloodworms: Bloodworms are another ideal protein-rich food source for your aquarium. Corys will eat these guys up. Having either frozen bloodworms or freeze-dried bloodworms will work when feeding your corys and your tank mates.
Types of Corydoras Catfish
There are Hundreds Of Corydoras Catfish but we will cover 5 of our absolute favorite corydoras. For all the Corydoras we will be discussing their PH are the same. The PH corydoras love is between 6.5 and 8 this alone is awesome for the corys and us. They can withstand so much making them a favorite for beginners.
The Sterbai are an absolute favorite mainly for their very cool designs. They are not used for nano tanks since they can get up to 3 inches so they aren’t one for Nanos but the next one on our list is a favorite for Nanos.
Their name means yes they are going to be much smaller than the Sterbai. The Pygmaeus will get up to an inch making them a favorite for nano tanks. Just like other corydoras, they are a community fish that is very social. Having more than one of these little cuties will actually help them live longer than if there were only 1. Safety in numbers is a BIG thing for all the Corydoras.
Habrosus can get a bit bigger than the Pygmaeus but not by much. The Habrosus have a more dotted design pattern on their bodies. Habrosus are peaceful fish like the rest of the corys. The main differences between the types of corys are their designs and size but other than that they are all pretty much the same. The price of these guys is $5 or less which is a HUGE plus.
The Barbatus is a unique type of corydoras since they prefer cooler waters down to 67 degrees. Having no filter is good for these guys unless u may have a cold winter going on having the heater will not benefit them.
The Barbatus will have a golden head and body undertone. Having these guys with some cool water tank mates will be awesome. The main problem with these fish is the price! Geez, they can be $30 apiece! So having more than one of these guys can be a bit much.
Orange Lazer Corydoras
Yes, the name is crazy but it goes well with the corys for their awesome orange coloration. The Orange Lazer Corys are not that different from their family other than their color.
These Orange Lazers cost a good $15 to $20 but they are worth the cost!
How To Breed Corydoras Catfish
Corydoras breeding is a very interesting fish to breed because it boils down to the type of corydoras. In this how-to, we will talk about the most common types of corydoras.
When you first begin breeding corydoras having a good group of about 6 corydoras is ideal for them to feel protected and more secure. Having a good tight nit community is good for the safety in numbers.
For the Corydoras it’s the exact opposite of regular fish with the ratio of males to females. There need to be more males than females because the males will lose track of the female and start looking for more females to breed with. Having more males will limit this problem.
Most fish need a good balance of beneficial bacteria, to say the least, so having good bacteria and good water conditions will be ideal for the corydoras to breed.
Dieting is ideal for these little guys but especially for breeding. Around 74 degrees is ideal for breeding. Fish food that doesn’t have primarily fish meal will be good since the meal is just a bonding factor for the food.
Live foods are a good quality food source to get your fish to spawn. Blackworms, bloodworms, and brine shrimp YES!
