Pictus catfish (Pimelodus pictus) is a tank fish of average size, it is a member of the catfish family Pimelodidae.
Habitat in the wild
Birthplace of Pimelodus pictus is in South America. It is spread over Amazon and Orinoco rivers within Peru and Columbia. It is often confused with an upside-down catfish, but these are two completely different species, Synodontis dwells even in Africa.
In the wild the fish inhabits in lentic waters and as a rule lives where the water flow is slow, the bottom is sandy or muddy. This is a schooling fish and you can often encounter it swimming in large schools.
This fish is a benthopelagic one. It requires clean freshwater. This is a bottom dweller that becomes active when it starts getting dark. The fish feeds on small fishes, snails, prawns as well as larvae, fruits, insects, detritus. This catfish uses its barbels to find the prey.
In a tank this fish can grow up to 16 centimeters (6.3 in) long, but as a rule it is 11.0 centimeters (4.3 in) long. The fish lifespan is 7-8 years.
Pictus catfish has a tall elongated body with a tall triangle dorsal. The fish has three pairs of short barbels and one pair of barbels on its upper lip is long. These barbels help the fish find food in very muddy water.
Pictus catfish has a bilobular tail fin with deep cut-out. The main color of the fish body is silvery with round black spots both on the body and fins. To move the fish from one tank to another use a dip net, since the fish has very sharp spines on the first rays of its pectoral fins that may cause very painful injury.
Difficulties in keeping
This is a simple fish in terms of keeping in a tank, but it becomes active only in the evening and at night (as it does in the wild). Another thing is that this catfish just like the others can hunt small fishes at night.

This is an active tank fish and it needs a large and spacious tank with a lot of space for the fish to swim. Minimal tank capacity for this catfish is 200 liters (44 gallons).
We should mention that even in a tank of 200 liters capacity you can keep several pictus catfish species, since the fish is not a territory dependent one and it can easily dwell together with its kind. It’s better to keep them in a small school of at least 5 species.
Tank water parameters to keep pictus catfish should be the following: water hardness 6-15°, рн 6.0-7.5, water temperature 22 — 26°с.
Tank lighting should be dim and not bright, especially there shouldn’t be any bright light on the tank bottom. The thing is that the fish will hide during the day if the tank is lighted too brightly. However, if the light is dim it’ll be active.
There should be lots of shelters and nookeries in the tank, where the fish can hide during the day. This is a crucial thing if you want to keep pictus catfish successfully.
It’s better to create a biotope that resembles a river – with snags, sand and stones. Since it’d be rather difficult for tank plants to survive in a shaded tanks, it’s better to use undemanding kinds of tank plants – java moss, anubias nana.
As for the water filtration, it is very important and it’s better to use a medium powered external filter. Due to it you can create moderate water flow, that the fish likes a lot.
It is of crucial importance to renew tank water and clean the bottom regularly, since pictus catfish is very sensitive to ammonia and nitrates content in the tank water.
You should be especially careful when transporting the fish since it has poisoned spines that can stab a package and hurt the owner. The wound isn’t toxic, but it is quite painful and may hurt for several hours. Therefore, you mustn’t touch the fish with your hands! To catch and transport the fish use plastic containers.
It’s not a troublesome thing to feed pictus catfish. Just like many other catfishes they eat almost everything they can swallow. In the wild the fish is omnivorous, it feeds on insects, fish juveniles, algae and water plants.
If you (just like me) regularly feed your fish with artificial food, then the links below will be very helpful for you. I know what it’s like when you pet fish die because of low quality food or get ill due to infection ingress into the tank with live food.
I’ve chosen the best food you can buy on Amazon.com for this kind of fish. I myself give some of this food to my pets and as for the rest I’ve heard and read lots of good reviews. Yet, all of the food is of high quality and it is the best one for this fish kind as well as it keeps the tank water clean.
This catfish is a predator that will eat everything it is capable to swallow if it comes to small sized fishes. Though the fish demonstrates completely peaceful behavior towards large and average sized fishes.
You should keep the fish only with equal sized tankmates. All small sized fish species like: guppies, neon tetra, cherry barb will be eaten. Pictus catfish gets on well with clown loach, rainbow shark, tiger barb and other large or fast fishes.
How to tell between pictus catfish female and male is still unclear. There is an opinion that the females are larger than males and they have fatter abdomen.
There is no reliable information about this fish breeding either. Even the behavior that looks like a spawning one was quite seldom seen.
