ANSWER: What is your tank size? This is a very important question.

For three full grown Oscar Cichilids you will need a 150-200 gallon aquarium with double or triple filtration. As of now they are juveniles and for a grow-out tank a 75 gallon is needed and then when they reach the 6-8 inch mark move them to their permenant aquarium.

It sounds more like white-spot fungus or hole-in-head Cichlid disease.
Ich has the appearance of dandruff, white flecks floating around and gathering on the fish, not mottling or skin deformation.

You'll need to give me your water parameters as well.

Poor water quality causes white-spot and Ich.

I can help you more if you could possibly provide an image of your sick Oscar and fill in a couple of my questions.

I'll be glad to help you in any way, I've owned many Oscars in my time and they are a great fish to own.

i have attached a image is quite blur.. sorrry..
thank sooo much again

30 gallon is much too small for a full grown 1-2 foot Oscar. I understand that there can be confusion with Oscar's as common chain petstores sell them as "30g" minimum fish.

You don't have to give me the water parameters the tank size gave me a good idea of what's going on. You'll want to set up the 70g, use the existing filter cartridge to cycle the aquarium the water does not have much of the bacteria needed to cycle the new aquarium. Put in a few decorations and wait four to seven days.

You'll need to test the new tank's water to see if it is fully cycled which means: No ammonia, no nitrites and 20-40 PPM nitrates.

The water may look and seem to be good clear water but it all depends on the ammonia, nitrites, and nitrates that are going down chemically.

Water quality is the best medicine you can give and then decide treatments.

Once they are settled in the aquarium continue to use heat. Make sure you have double or triple filtration on the 70 gallon as well so the water quality remains perfect. Weekly do 30% water changes w/ gravel siphon.

While you are setting up the 70g do a massive water change on the 30 gallon aquarium, 50-65%, and suck up as much crud at the bottom as you can. Oscars prefer sand or bare bottom aquariums as with gravel they shove it around into piles which creates sewage build up and small stones doesn't hold the nitrifying bacteria (the bacteria that stablizes and cycles the aquarium) very well.

I would do this as soon as you can and then I'll help you with future steps if needed.

The Oscar isn't terribly mottled with white spot, I believe that if you get the 70g running quickly you'll be able to save them.

My knowledge of fish ranges from freshwater and saltwater fish compatibility and care from easy livebearers to monster fish. I can help you set up a simple freshwater aquarium to a complicated reef tank. I would be pleased to assist anyone who is new to the aquarium hobby.


I have been in the aquarium hobby for eight years mostly dealing with large and small aquariums. I keep mostly monster fish (Arowana's, Large Cichlids; Oscars, and freshwater/saltwater eels specifically) but now that I am in college I am keeping a 30 gallon tropical community and a 45 gallon brackish aquarium while my father tends to the big monsters I left behind.

I'm on YouTube! My 30 gallon community posts are the only ones that are up so far. My Brackish tank is next! I'm on Yahoo Answers:

I am currently in college aiming for a job in Marine Biology.
