My oscars are always attacked by fungus...wat should i do.?

Sounds like they are fighting, damaging each other, then the fungus takes root, then beware of secondary infections.





Water quality should be kept high, as they produce lots of waste, best bet is to use an external filter.


If you have a few Oscars, Then is your tank big, if it is, help them define territories, by placing physical objects around, decor and plants, this helps them establish territories, otherwise the dominate fish will see the whole tank as its own.





Just how many do you have anyway and what size tank do you have ?My oscars are always attacked by fungus...wat should i do.?
how big is your tank? how many oscars are in the tank? more information would help but i'll try my best to answer.


you should take your oscars out into a seperate tank that has been treated and cycled. then take out the water in your tank and leave no water back. then restart the tank by cycling the tank, treating it and so on. then add your oscars back and they should be fine. if you have a small tank(55 gallon) you have a tank that is too small to house ';oscars';. you should have a 100 gallon if you want to keep more than one. thats probably why they get sick also because the oscar are producing too much waste which can create diseases and parasites in a small tank.


hope this helps
