Catfish are great additions to most
community fish tanks. But beware some catfish can grow up to two feet in size and will quickly overtake a 10-gallon tank.
The problem is many catfish sold in stores are only a few weeks, maybe months old and far from full grown.
As a beginner, unless you know your catfish species really well you may accidentally purchase a common pleco catfish.
Imagine this…You get home with your small common pleco only about 1” in size add it to your 10-gallon tank.
Then, over the course of the next 12 months, it just keeps getting bigger and bigger eating everything in your tank.
Eventually, you’ll need to find a new home or worse it may die.
“BIG” mistake. Don’t let this happen to you.

Lucky for you we’ve found four of the best small catfish for a 10-gallon tank to save you from embarrassment.
Here’s the list.
1. Corydoras Catfish Care level: Easy
Max size of fish: 2.5”
Temperature range: 72 – 78 Degrees Fahrenheit
PH range: 7.0 – 7.8 Corydoras catfish are a small, peaceful bottom dwelling catfish that are very social and love to school.
Most cory cats can live just fine alone but do best in groups of 3 or more, which is perfect for a 10-gallon tank.
Cory cats will bring movement and excitement to the bottom of your tank as they dart up to the surface for a gulp of air.
With the many different types of cory cats available
You’ll have a hard time picking just one for your tank.

Bandit Bronze Panda Julii Pepper Skunk Three stripe 2. Otocinclus Catfish
Beer Powered Care level: Easy
Max size of fish: 2.”
Temperature range: 72 – 79 Degrees Fahrenheit
PH range: 6.8 – 7.5
The Otocinclus catfish is another great catfish for your 10-gallon aquarium.
You may see them called everything from:
Otos, Oto Catfish, Otto Cats, Ottos, Dwarf Suckermouths, Dwarf Oto, Dwarf Ottos, Dwarf Suckers, Algae Scrapers,
Basically, they all mean the same thing.
They are very, sensitive little guys and will do best when added to an established tank.
The Oto will rarely grow larger than two inches but they do like to be kept in a group of at least 3.
They are great
little algae eaters feeding on algae growing on any hard surface or plants.
So a heavily planted 10-gallon tank would be ideal for the Oto.
3. South American Bumblebee Catfish (Microglanis iheringi) Care level: Easy
Max size of fish: 2.”
Temperature range: 70-77 Degrees Fahrenheit
PH range: 6.5-7.5
The bumblebee catfish is a bit of a push in a 10-gallon tank as most will recommend that one bumblebee catfish should be kept in at least 20 gallons.
That said, it will only be approx 2″ full grown so it should be fine in 10 gallons with lots of hiding places and plants.
This catfish likes to hide in the lower parts of the tank in the roots of plants, driftwood, and rocks. It’s also nocturnal so typically will only come out at night to feed.
Be careful with small fish, as the bumblebee has been known to eat anything that it can fit in its oversized mouth.
So small tetras like the
Neon Tetra and rasboras may disappear overnight if you keep them in the same tank.
Its regular diet is sinking pellets, frozen and freeze dried foods.
Overall it has a very quiet and peaceful demeanor great for a 10-gallon tank.
4. Upside-Down Catfish (Synodontis nigriventris) Care level: Easy
Max size of fish: 2-4”
Temperature range: 72 to 79 Degrees Fahrenheit
PH range: 6 to 7.5
The Upsidedown catfish is another option for a 10-gallon tank but you may only be able to keep about 2 of them since they can grow up to be almost four inches.
The upside down catfish is named after the way it swims…upside down. Apparently, this helps them eat easily from the surface of the water.
That said, they can be found swimming normally to eat food from the bottom of the tank.
The best type of tank for the upside down catfish would be well planted with lots of heavy broadleaf plants. Keep driftwood, rocks and caves also provide great places for them to hang out.
The upside catfish is most active in the evening and night.
