Bolivian Buntebarsch (bolivian Ram)

[November Rain]

I have had this fish for 3 years... He was always playful then he began to slow down staying close to the bottom and where he cant be seen


He wouldnt eat and now he is belly up, swimming like he is paralyzed on one side

He had good color

no red gills, no clamp fins no white spots

the water is as it has been for 3 years


now after a few days he is thinning and I know he is dying
but I dont know why


he is in a huge aquarium about 6 feetx 3 feet wide and 3 feet depth (about)
he is about 3-4 inches long

any idea what is happening

the only other fish is been in there just as long as him
a pleco , 3 siamese

they dont bother him never have but my albino cat fish died the same way a month ago
both the catfish and the bunte barsch and the pleco all ...we got at the exact same time 3 years ago
the others we got 2 years ago

now the buntebarsch (brain) and the albino catfish (pinky) stayed close together it was cute how they seem to be schooling but were different

they were the oldest and now I dont know what is going on

Nothing about the tank has changed
Nothing

no fish been added
ph, o2, nitrate, nitrite all same as always (just to name a few things)

anyone have a clue as to what is happening?

I would think 3 years is an average lifespan for a Ram, not sure about the cat fish though.
