Oscars

[2fishy]

Ok right I have a customer who has a 600L tank with a cannister filter on it. he does 25% water changes on it weekly.

Now in this tank he has 2 approx 20cm oscars and 2 approx 20cm pacus and one syndontis.

The oscar has like almost bite mark looking holes on its his head. is this hole in the head?

One pacu quite often gets a white film over one eye (always same eye and same pacu) and it sometimes gets fluffy, im assuming this is a fungus?

How do ya treat these?

thanks

the cloudy eye is often from bad water conditions im told (bacterial) and with only 25% a week with these fish its likely it is bad water. i would tell him to up them to around 40% at least a week (could do 20% twice weekly etc) and im sure youve already notified him those pacu arent going to be able to stay in that tank :lol: if he improves the water quality then he should see that cloudy eye dissppear in no time, if not im not sure what to treat it with, perhaps something like Furan2?. apparently melafix should be avoided with pacu, im not sure if they have sensitive skin or what but i remember reading someones pacu got 'dry' cracked skin when they used that :-? if his filter isnt doing at least 5x per hour on the tank i would also suggest he gets another also. pacu are apprently not very efficient when it comes to digesting their foods and create alot of waste like oscars so need good bacteria colonies to be able to break down all that waste with regular manual removals of it

its hard to tell without seeing the oscars if its HITH. bad water conditions are one of the main contributers of it, plus oscars are prone to it. what is the oscars diets like? pacu can be nippy fish so he may have gotten bitten, HITH doesnt show up over night but slowly gets worse and worse.
