Any symtoms to go on.
Do they look pale or darker in colour,
Are they listless and lethagic.
Any sign of flicking and rubbing.
Bala sharks need larger tanks how big are they.

No i have not noticed any of these but have noticed 1 has redish fins and they are about 2 ins

Reddish fins can be bad water quallity to septicemia.

What size are they. I noticed this at pet stores. Some will sell 2-3 different size ballas. The smaller ones are pretty delicate, but the 2-3 size always works a charm.

Thanks but i test water every day and do a 25% water change every week what is septicemia and how do you treat this ?

Septicemia is blood poisoning, caused by dirty water and bacteria entering the fish through wounds,
Septicemia hard to cure once its advanced.
Need location for a med.

They are about 2 ins maybe little smaller

I am on the wirral what can be wrong with water if ammonia nitrite and nitrate are all fine

Its septicemia if water quality is good.
Anti internal bacteria med by interpet, but if the septicemia to advanced the med won't cure it, as its only good on mild bacteria infections.
Antibiotics but only to be used in issolation as the antibiotic wipes the benefical bacteria out in your filter.

thanks alot would these fish have septicemia when i purchused them and will it spred to other fish

They could have already been ill at the lfs, if fish have septicemia its best to issolate them as the bacteria from the fish can enter the tank infecting other fish.

I have no means of issolateing these fish as i have only this 1 tank anything else i can do ?

You will have to medicate the whole tank and hope for the best.
