Pictus Catfish Care Guide

Pictus Catfish

Catfish are one of the most sought-after freshwater aquarium fish for beginners setting up a new home aquarium. One of the most common species of catfish you will find in aquariums all across the globe are the Pictus Catfish.

Naturally found in shallow flowing waters of the Orinico and Amazon Rivers, these small catfish are pretty easy to distinguish from other types of freshwater aquarium fish.

Their whiskers are extremely long, as you would expect from any species of catfish, and their fins and tail are sharp, allowing them to swim at an incredibly fast pace. The colors you will typically see on a Pictus Catfish are silver, with black spots across the entire length of the body. The dorsal fin is generally black in its entirety, but as with all fish, there are often some exceptions.

The ‘whiskers’ that are found on all species of catfish are actually called barbels, and they are what the catfish use for navigating in muddy waters, as well as feeling around for any spare food that they can get a hold of.

Watching the Pictus Catfish navigate the tank with its extremely long barbels is one of the reasons why they are such an entertaining fish to own.

Our comprehensive Pictus Catfish care guide will explain everything you need to know before adding this beautiful creature to your own aquariums. Let’s start with the aquarium itself…

Pictus Catfish Housing & Tank Set Up

best catfish for aquariumAs the Pictus Catfish is a shoaling species, in the wild, you will find them in large groups, so it’s important that you keep this in mind when setting up your home aquarium to house this species of fish.

They rarely grow anything over 5 inches, so if you are worried about them taking up a tonne of space, don’t be!

The minimum tank size that we would recommend for the Pictus Catfish is around 50 Gallons. We recommend keeping them in groups of at least 5, preferably more.

With all that being said, the Pictus Catfish is a very active fish, so the more room that they have to swim around in, the healthier and happier they will ultimately be.

There are a few important pieces of information that you must keep in mind when setting up housing for your Pictus Catfish. Firstly, this species of fish is native to the warm waters of the Amazon River, so the temperature of the tank water must reflect that. We recommend anything between 70 – 80 degrees Fahrenheit (20 – 27 Celcius), with the pH set to around 5.5 – 7.0.

The next thing to keep in mind is that the Pictus Catfish is primarily a nocturnal fish, but a dimly lit environment may encourage activity during the daytime. Keeping your aquarium dimly lit is absolutely crucial if you want to keep your Pictus Catfish as happy as possible.

As well as dimly lit aquarium lighting, you also want to make sure that you have plenty of shaded areas and plants for them to hideout in. Driftwood, artificial rocks and clay plant pots are great ways to provide sufficient shade, and hiding places.

Low light plants that we would recommend are Hornwort, Java Moss or any other moss varieties that are available to you.

In terms of the type of substrate you should use, you want to try and imitate a river bed as much as possible, so a sandy substrate will be optimal. The one that we use regularly is Nature’s Ocean Bio-Active Aroganite Live Sand

Pictus Catfish in the wild are constantly at battle with water currents, so in order to replicate their environment properly, you could add a Circulation Pump 

For filtration, any good quality filtration system will suffice, but the type we would recommend would be a hang on back filter, simply because of the current that they can create. Pictus Catfish are notorious eaters, so they produce a lot of waste. Combine that with their sensitivity towards nitrates, and you will understand how important it is for your filtration system to be as good as possible.

We recommend having a good quality water test kit on hand to make regular tests of your aquarium. The one we use (and the best on the market) is the API Freshwater Master Test Kit

Pictus Catfish Diet

In the wild, Pictus Catfish are omnivorous by nature, so they will eat pretty much anything that comes their way. This makes our job as fish keepers a whole lot easier!

The base of your Pictus Catfish’s diet should be a high-quality sinking pellet. Since the catfish like to spend the majority of their time weaving in and out of plants, and hidden within shaded areas, it’s important that you choose a sinking food, which is easy for them to find.

If you are unsure about which sinking pellet food to purchase for your Pictus Catfish, then we would highly recommend Hikari Sinking Carnivore Pellets.

In addition to a quality sinking pellet, we would also recommend including some invertebrates in their diets, such as brine shrimp.

Frozen foods (and live foods) are also a good treat for your Pictus Catfish, and we regularly feed our own a bunch of different ones such as Daphnia, bloodworms and blackworms.

As we previously mentioned, the Pictus Catfish is an incredibly greedy fish, who will not hesitate eating other smaller fish in your aquarium if they are not fed enough, so make sure you are feeding them some good quality food, and you are feeding them often.

Neon Tetras are an example of the types of fish that the Pictus Catfish has been known to munch on when it gets hungry.

Breeding Pictus Catfish

Unfortunately, it’s not really possible to breed a Pictus Catfish in a home aquarium, simply because of the lack of open space that the fish needs to reach its full sexual maturity. If you are housing your Pictus Catfish in an enormous tank, then it may be possible, but if you are working with anything less than a couple hundred gallons, then the chances of you seeing them breed are incredibly slim.

On top of that, the Pictus Catfish is very hard to sex. The females are often said to be the larger of the sexes, but there is nothing else that really distinguishes the differences between them. We have been keeping Pictus Catfish for several years, and we still can’t identify what sex they are.

Suitable Tank Mates

How To Care For Pictus CatfishThe Pictus Catfish is generally a non-territorial and non-aggressive fish, so you should have no problems keeping them with most other species of fish.

The only issues that we have found is that the Pictus Catfish will not hesitate eating smaller fish if they are in the least bit hungry, so keeping them with fish that are small enough to fit into their mouths is always a risk.

Pictus Catfish are also fast, vigorous swimmers, and their fins and barbels are sharp, so if you are housing any slower swimming fish in your tank, then they could potentially cause some issues. It’s not uncommon for the barbells to accidentally injure other fish in close proximity.

The sharp barbels are not only a danger to other fish in your aquarium, but also to yourself when trying to transport them from tank to tank. The long barbels are sharp enough to pierce a humans skin, and the venom they possess, while not harmful to humans, can leave us with a lot of pain and swelling for several hours.

When moving the Pictus Catfish from tank to tank, we recommend a plastic container of some sort, or something with smooth, hard edges that are impossible to break. Using plastic bags which is usually common practice is a big no-no, as one prick and the bag will easily split.

One other recommendation is to never use a fishing net to transport the Pictus Catfish. The barbels can become tangled in the net, causing damage to the fish while it forcefully tries to break free. Damaging the barbells or any of the fins could result in a slow painful death.

Common Pictus Catfish Diseases

The Pictus Catfish, like most other species of catfish, is a scaleless fish, which you probably already know means they are more susceptible to common aquarium diseases such as Ich and White Spot.

Other diseases may also be present if the water conditions are not maintained, and the fish is not as healthy as it should be. Pictus Catfish have been known to go downhill very quickly at the onset of disease, often leading to sudden death. For this reason, we would not recommend the Pictus Catfish to absolute beginners.
