One Tiger Barb found upside down and then died

[vijayw]

This morning, one tiger barb from the school of 7, found swimming (neither resting at bottom nor floating at surface) upside down.

Other fishes - One Black Angelfish and Tinfoils were going near to it -pushing it, playing with it, possibly picking it? But then I moved it immediately to a bowl, filled with the water from main tank. Unfortunately the fish died within 10 mins.

I then noticed the behavior of other fishes in the tank, all behaving normally.

Since today was my work day, I am planning to do some water change tomorrow.

Any idea what happened to the tiger barb?

Tank: 30 gn
Tank mates: 4 Tinfoil, 7 Tiger barb, 1 Angel, 1 Sucker, 4 koi

Sounds like a swim bladder infection

Thanks -

I searched internet and removed that fish in another bowl with same water from main tank, before i could treat it with rock salt or peas, it died.

Hopefully its just one off a case and case of overeating?
