Unknown Illness

My angelfish has just developed a big silver patch on both sides.
He cannot swim properly and floats around on his side at the top but is still alive.
I attached a photo, can someone please help?

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

The fins look tattty any fish been nipping the angels fins.
What do you feed the fish.
What does it look like when the fish goes to the toilet.

As for the silver patch don't know what that is. Sure it isn't the angel markings.
Any signs of flicking and rubbing, excess mucas, laboured breathing, or gasping, darting or erratic swimming.

35L tank with a parrot fish, a gourami and a rainbow shark.
There has been no change in any of the levels, they are all normal for my tank.
Only the dorsal fin is tatty, that only just developed since the patch appeared. The other tatty looking bits are just transparent patches in the fins.
Feed my fish Tetramin flakes.
Have not seen the fish doing the toilet for a while.
Definitely not the markings, had it ten months and the patches only appeared alst night.
It doesn't flik or rub against anything. It acts normal except for the fact that it just floats on its side.
Breathing etc. is normal.

Could this be an internal bacterial infection?

Not one of those fish should be kept in a 35 litre tank.

For an angel fish you need at least a 20 gallons tank.
Rainbow shark 45 gallon tank.
Gourami about 10 gallons.
Parrot fish not sure but they probably shouldn't be kept in a 35 litre tank.

Take a sample of your water to the lfs and ask them to write the readings down for you.
I would rehome all the fish and stock it with fish for that tank size.

agree with Wilder,
I'm guessing its Ammonia pioisning, you will need test readings

Thanks for the advice!

Research the fish before you buy as not all lfs tell the truth.
Good Luck.


The filter won't cope with the stocking either. The fish will just keep dying of bad water quality.
