Paroon shark behaviour

[Billy_boy]

Hi mates
I have a pair of 8-10 inch paroon shark in 400 liter aquarium. For last a few days, I have noticed, the shark stands right in front of Air filter (1500 l/h) and keep swimming in front of Bubbles pressure. Is it normal, is he enjoying or is he getting disturbed. Only one shark do that.
I have attached a pic, though not clear but it will give you an idea what's I am talking about.

Regards

Iv got 2, ones about an albino around 15" and the others only around 7-8". The albino does this from time to time, nothing unusual. He also gulps air from the surface which iv found out is not unusual either

Some fish like to swim or hover in current, i would also recommend getting a larger tank soon.

Can we get a full tank shot?

Hmm. That tank is very cramped being a cube shape, it might be a way to exercise (and a sign that it needs a larger tank)

Pangasius sanitwongi grows huge,it lives in shoals and is very active.I have never seen them do well in aquariums for long.They damage their eyes and mouths constantly rubbing them up the sides of aquariums. They always look stressed and never seem to adapt well to life in a fish tank.
A tank of 4 meters by 2 meters would become too small to house these catfish properly.
A species best left to the wild or the largest of public aquariums.

These catfish can grow up to around 8 feet in length.
A species that can't really be accommodated for in home aquariums. A fish I always pity when I see them for sale.

It was an inch or 2 when I got it. It was in small aquarium first, and now I got a bigger one, but from you guys suggestion it seems it will soon become too small for him.

It really will.If I were you I would take them back and get something more suitable for life in a fish tank.
