Origin: This catfish's ancestors lived in the Mekong River Basin in Thailand. But these fish were spawned and raised on a famous fish farm.

Maximum Size: In aquariums, Black Ear Cats can grow to be over 52" long, including their tails, and sometimes larger.

Behaviors: They like to eat and are constantly moving and looking for food.

They will, like most catfish, eat any fish that fits into their mouths.

Compatibility: Some recommended tank mates include other large fish such as Arowanas, Datnioides, and perhaps large Cichlids.

Feeding: Premium Fish Food Pellets.

Water Conditions: Black Ear Catfish tolerate of a wide range of water conditions.

Probably a pH of about 7 with moderate hardness is best.

Most water in the US is different but seems to be OK, so it's probably best NOT to adjust the pH or the hardness of the water.

Here in our facilities the water is hard and the pH is usually about 7.8.

We ship them in this water.

Aquarium Size: When less than 3" long they can live in 30-gallon aquarium, but when fed well, they will soon need a larger aquarium and eventually a much larger aquarium.

Decor: these catfish do not need gravel, and a layer of gravel more than 1/4" thick will usually fill with bits of uneaten food that will contaminate the water.

Live Plants: are beautiful, improve the water quality, but will be bulldozed out of the way by these catfish, as they search the bottom for food.

Aquarium Filter: Bio-Wheel Filters are highly recommended.

A Penguin 200B in an aquarium with 30-gallons is OK, when these catfish are under 3".

But eventually they'll need to live in a much bigger aquarium with a much bigger filtering system.

The addition of Lava Rocks will keep nitrates in the ideal range.

Life Span: this catfish can live for several years, or maybe many years with excellent care, including excellent water and premium fish foods.

Gender: As they mature, the females will fill with eggs and get plumper. But it's usually not easy to see.

Breeding: there are no reports of this catfish being spawned in an aquarium.

But they are probably being spawned as food for humans in large ponds in Asia and elsewhere.

Popularity: Not very popular but more popular than we'd expect, knowing how large they grow to be.

Names: This species name is Pangasius hypophthalmus.

Variations: There are no variations known to us.
