More or Better filtration. There is no such thing as to much filtration especially with Oscars. BTW what size tank and what filter(s) do you have?

Filtration and waterchanges.

You can help us....help you by answering 4 questions for me Smile

How big is your tank?
What filtration system do you use?
What fish are currently in the tank?
How much and how often do you do waterchanges?

I have a 55 gallon tank and a 40-60 gal power filter from aqua tech, I think.

I change the water 10% every 2 weeks
(don't worry, they are going to go into a larger home when they grow)
How often and how much do you have to change the water with these guys?

As you state your getting a larger tank in the near future, I'm not going to harp on that. But that filter just simply is not enough to handle the bioload of a 55G muchless a 55G with messy fish. I would STRONGLY recomend a canister filter such as the Rena XP3, or in the absolute minimum a secondary filter like the one you currently have. Also do atleast 30% weekly waterchanges, you may need to do more depending on how large your oscars are....testing your water will let you know if you need more. If your nitrates are over 20ppm....you need to do more frequent waterchanges and of larger amounts.

Also the absolute bare minimum for these fish you have is a 90G tank....which is also a 4ft tank so it won't take up much more room of your home. I think the sooner you can get them into a tank this size the better...and for a tank of that size Id run atleast 2 big power filters(like 2 of your aquatechs) and a large canister(like the previously mentioned xp3).

Just curious how large are your fish?

THANK YOU VERY MUCH MCHRKiller. I had no idea it would take so much to clean up after the messy guys ^^
But, question, what is a canister filter? I have heard of these but never got deep into them
Are they very expensive?
Also, is it a bad idea to feed them cichlid sticks, it seems every time I feed them one of these they expel pieces everywhere
is there a wiser choice of food for them? thanks

Its essentially a bucket of media with a motor attached to it, it draws and replaces water to your aquarium via hoses, look at the products section on this site to look at some various types. Oscars are large bulky messy fish, they require a lot of filtration and a lot of maintenace. If you purchase your canister online...they arnt to bad, I know that www.bigalsonline.com has the XP3 canister right now for $100. Try some pellets...oscars usually don't make such a mess with pellets. Hikari gold pellets are really good for them, really brings out their colors as well Smile

Hey,

I read one of your other topics, the one about your sick tank. By only having a few mollies in there, and then putting such large fish in, you may have started it cycling again and the cloudiness would be a bacterial bloom. If that's what it is, it will clear itself up, but definitely add more filtration.

Doc

The filter is not big enough for the tank size. The rule I use is to have the max rating of the filter, reduce it by 30% and it should be bigger than your tank size.

In your case, the max reading of your filter is 60g, reduce it by 30%, it is 42g, much smaller than your 55g tank size.

Remember this rule is for normal fish load. For mess fish like oscars, you should have much bigger filter than that. The fact you have cloudy and smelly water tells me that your filter is not big enough and you are not doing enough water change for the tank.

I would go as other people said, upgrade your filter and doing at least 30 to 40% weekly water changes.
