Corydoras Catfish Species Q&A

The Catfish species line of Corydoras has over 100 different types. These catfish are super popular amongst the aquarium community due to their cleaning abilities. Keeping fish tanks clean can be an intensive task by itself. Bottom feeders like the Corydoras really make our jobs easier by eating uneaten particles that break down into water waste.

Corydoras CatfishCory Catfish Food?

The Cory is only a herbivore and loves eating left over fish food that went uneaten by the other fish. An aquarium owners fear is algae and the Cory just so happens to love it. It’s no wonder these catfish are so popular in the aquarist community. You could save hours of time scrubbing scrubbing algae just be having a couple Cory catfish in your aquarium. Sometimes the amount of algae in your aquarium is not enough food. Buy some algae wafers for your Cory just to make sure they are getting enough food. Some human food vegetables work well too.

How many Cory Catfish in my Tank?

Many are unaware that Cory catfish actually prefer to be in schools than be solo. For a 30 and above gallon aquarium, have a minimum of 3 Cory catfish. They will be much happier than on their own. They are a beautiful fish and have quite a personality when schooled up with others of their kind. For anything aquarium size less than 30 gallons, you may want to only get two. Their schooling habits are raved upon by others to be a very beautiful site. Males and females might mate to make more so research physical differences of males versus females to stop mating from occurring. Other fish will most likely eat the eggs but sometimes fry do survive. Just a side note to account for.

Water Temperature for Cory Catfish?

The Cory prefers the same temp range as most freshwater fish. That 74-80 degrees Fahrenheit mark is what’s needed. That’s what make them so easy to care for. You basically just drop them in and try to keep notice if algae levels are low to give them artificial algae food then. The algae food for them is still algae but its just not naturally grown in your tank of course. You want to make sure they are kept in that 74-80 degree mark. Too cold of temperatures might put them in shock and too high of temps might cook their organs enough to shut down. Don’t take water temperature too lightly.

How Big in Size? Cory Catfish?

An estimated full size of 2-3 inches is normal for the Cory Cat to reach. It’s not a huge catfish like some of its near cousins. That small in size also makes it very easy to have 3-5 of these in your fish tank. Like said before, they love to be in schools and have a lot more fun when their species are near them. The Cory is one of the easiest fish on the planet to care for and can really help take some of the hard work off your hands a far as cleaning your fish tank.

There are so many similar catfish species in this size that I’m finding it difficult to choose a species out for my community tank. I’m stuck between the Otto and the Cory as of now. It’s cool to have such a variety but its really becoming a head scratcher for me on choosing which type. At this point I might just flip a coin to choose for me.

A Cory is going to eat more decaying food that was missed by the fish than its near friend the Otto catfish. They are both good choices but I would personally choose a Cory just because they will clean more and I have had them for years with no issues. The Otto is more a leach style fish that doesn’t move much it seems.

An Otto catfish will eat more algae on the glass then a Cory. But then a Cory specializes in eating decaying food in the substrate and rocks. I would say to get both types of catfish for the ultimate community of well rounded habitat. I have a 30 gallon with a bunch of each catfish you speak of.
