Fish went from lethargic to dead in 24.

I've lost a parrot last night any ideas on what could have caused it.

Water params are OK.

Yesterday morning, noticed one my parrots acting strange, just not reacting to anything. Acting and swimming very still like, seemed like he was very focused on trying to breathe properly.

He was breathing quite heavy, and seemed to cough or choke, every 4 or 5 flaps of breathe he did like a double flap.

Eventually he settled at the bottom of the tank just leaning on a rock, eyes not moving much at all and just focusing on breathing, he slowly had trouble keeping balance.

At night this worsened and he started to really pale, meanwhile losing his ability to float upright displaying typical symptoms of swim bladder.

So I put him in a breeder box and kept him upright for the night and unfortunately he didn't make it to the morning.

Now I'm thinking whatever happened was chronic, everyone else in the tank seems fine. But I lost another parrot about a month ago who displayed the exact same symptoms.

I looked at his gills and they seemed abit damaged, I'm not too familiar but seemed like there really wasn't much gill tissue.

Do you have a deep sand bed? Did the fish dig it up?

Fish are like dogs. They will dig things up and poison themselves.

Big water changes and check the substrate.

No gravel. After research Im leaning towards Gill flukes.

Seems to match the symptoms, breathing from one gill, lethargic hiding in corner.

Can swim bladder issues be a secondary effect?

regretfully may never no why, some times fish just up and die. Happens more with captive bred than wild caught, passed genetics issue, week immune system, bad feed, exposure to bad water, again can be anything, with out a necropsy just no way to know for sure.
