Glass Catfish ill

[c arri10]

Hello all.

I've five glass catfishes that have been in the tank (28oC, pH 6.5, KH and GH 3) for six months now, doing well, growing well.
They are between 6 and 8cm long.
Yesterday I noticed that the largest had a hugely distended body cavity, his entire front below the mouth is blown up like a baloon.
His is still swimming well, and feeding well as well.

What could be wrong with it? What would you suggest?

thanks for the help.

The swelling has stabilised , but he still has his body cavity blown up like a ballon.
He is still feeding well. Any ideas on what should be done?

Generally, water changes never hurt any fish [assuming the water used is OK].

Internal swelling often indicates internal bacterial infection, which can be very difficult to treat.

Good news, swelling gone down and fish now looking normal.
I wonder if it was an abcess or something similar.

Anyway, problem solved and all glass catfish are looking good.

thanks
