Angel Fish Lay On Side On Tank Bottom

[Prey]

we have two angel fish which are about 3.5 in diameter bodies - weve had them a year or so

when i got back today one of them is just lying on its side on the sand at the bottom of the tank - it looks fine, no damage or obvious problems other than breathing slightly heavily - the other one is as normal - just looking confused at its mate

the tank is a planted community, 260l, no other fish showing any problems, tested water and nothing is above normal

any ideas anyone?

Size of tank in gallons or litres.
How many fish and which type.
Water stats in ammonia, nitrite, nitrate, and ph.

Does the fish look bloated.
What does it look like when the fish goes to the toilet.
Can the fish maintain its balance in the water.
Does the fish turn upside down in the water.
Does the fish look pale or darker in colour.

Not looking good he might not make it.
Can you issolate him.
It could be a bacterial infecton but the med could finish him off faster.

thanks for replying

could move him into a smaller tank that is basically just ticking over with 3 neons in it but im worried that stressing him to move might not be worth it?

Hows the fish now.
Angels and neons don't mix as angels eat neons in the wild.
If he poorly he might not bother them.

Thanks for the replies - unfortunately he didnt make it - i decided not to move him but the next morning he had gone so still a mystery as to what caused it.
