Sea Catfish

Coral cats do better in groups of 5 or more. They grow to a foot so, a 125 ish tank would be a good size for a group of cats and a couple of other similar-size fish. Coral cats like staying in tight.
In the late 80's the Columbian Shark Catfish were sold as a full freshwater specie.
Finally someone knew what they were doing.

Mmmmm, not necessarily. Depends how big those are. Young Colombian shark (ariopsis seemani) cats shouldn’t start life in salt water. They naturally start life in fresh water and only migrate into brackish and even full salt as they age/ grow. Those look too small to be in full salt yet and keeping them eating well and stocky is harder if they go to salt too early.
My three were in fresh up to around eight inch before moving into brackish. By the time they were 14” they were in full marine along with the 2ft diameter bat fish, polkadot grouper, spiny puffer and snowflake moray but by then most of the group had been grown on and rehoused to a local LFS for their huge marine tank used for highlighting the big fish people should avoid as cute little babies.

Wow didn't know that. Unfortunately I yrs ago were sold and people who bought them didn't convert them to brackish as well as the Green Spotted Puffer and the Mono specie. There was no internet and magazines like Tropical Fish Magazines came out later. I personally used the Magazines for learning of freshwater and marine species.
Born in sea but lives in the rivers flowing to the sea...But i KEPT it in freshwater tank.It has name Long Whiskers Catfish.
Looks like the Colombian shark catfish, larger juvi or a subadult. They are known to be grown in f/w to larger sizes but only 1 in a million sold. I have a collection of data on this. IIRC, I've met 3 cases or so, of them getting raised to 1.5-2ft in f/w and perishing soon.
its latin name is Mystus gulio. This fish lives in Asia.When i had colombian shark catfish -it was very short lasting fish-he died after 2 months in freshwater...
Wow, great. Glad I was wrong about my guess. Your ID appears right to me. Interesting. This is the first time I come across a larger Mystus gulio specimen. They are one of the biggest Mystus not quite reaching 2 feet in length: https://www.planetcatfish.com/common/species.php?species_id=450 -- see remarks -- do you know if yours is from India or from SE Asia?
Your rare specimen deserves its own, journal-style thread so we learn more and better about your experience of keeping it.
It looks like a unique fish that prefers brackish water.
Looks like several species come under this name and the future taxonomy work may separate them.

| Easily characterized by its dull-colored body and very short adipose fin. There are several species currently identified as M. gulio: the true M. gulio is an Indian species that grows much larger than those from Southeast Asia, and is a more greenish (vs. grayish) color. | |
| Sexing | Males have an elongate genital papilla in front of the anal fin. |
| General Remarks | Primarily a brackish water fish that enters and lives in fresh water. In freshwater, it occurs mainly in larger water bodies (rivers and streams) with mud or clay substrates, and rarely found in smaller streams. |
