They do that ;) Being moody and sulking and all. Would think that is just normal behavior until he/she got used to you and the new surroundings.

Worrying a bit about the water quality though, looks like the tank hasn't been cycled properly before you put in the fish? Might be as well he's feeling unwell because of that additionally. Else ammonia and nitrite (NO2) should be zero, and the nitrate reading would be higher. So you should be careful not to feed the Oscar too much and really monitor your water parameters and keep the tank very clean by changing water often and vacuuming the gravel, else you might run into problems. Pay some attention to his breathing, eating and the look of the fins and skin. PH is fine.

There is an article on cycling a tank on here for some more info if you are not familiar with the chemical stuff and procedures.

If I were a guy, I\'d have probably needed only 30% of the amount of words to say this

I concur with metoo. Your water quality is quite poor at the moment. One of the most important things to remember when keeping any fish in an aquarium is that ammonia and nitrite are highly toxic. If fish are exposed to these two toxins for too long, two things can happen, they will either die, or they will suffer irreversible damage to many parts of their body, inside and out. Even though you may not seen the signs of damage, your Oscar/fish will be more susceptible to illness in the long-term.

I will reiterate what has already been said. Don't feed your Oscar too much for the time being. The problem you've got as you have got a very small tank, it won't take very long for the water to become polluted. I think you have got some bacteria are working in your biological filter, but it's not quite enough at the moment. Do a water change every other day, around 25%. And I would strongly advise you to get some stress zyme. This product will really help protect your fish against ammonia and nitrite.

The PH is fine
Increased temp to 75 deg
Added some stress coat as well.

Ammonia should be at -0
What level should No2 and No3 be at?

I want to thank all of you for all of the help, This site is awesome. Everything you want to know about Oscar's is here.

I plan on doing weekly tank changes, but my next question is when will I know to change the filter?

Which indicates a filter is in need of replacement? An increase in Nitrate or Nitrite

What sort of filter are you using? I think you need to have a basic understanding of how your filtration works. It seems as you are getting slightly confused (hope that doesn't sound like I am patronising you?)

Depending on what sort of filter you've got, you will have various substances inside. These can be made up of sponge, or in many cases ceramic type material. Normally filters have biological filtration, mechanical filtration and carbon. The biological filtration is what all your bacteria live on. This kind of filtration should not be changed very often. If you were to replace it completely, you would actually be removing the lifeline of your tank. In other words, there would be nothing to take care of the ammonia that the fish produce. The only filtration you should change is the mechanical filtration.. In fact, you can normally rinse mechanical filtration out which will save some of the bacteria that will live in this kind of media as well.

I know that some filters have cartridges that you can change. I'm not familiar with these that I would be very surprised if its biological filtration that needs to be changed on a regular basis, is more likely to be mechanical or carbon. It really does depend on how big your tank is, how many fish you can and what hyperfiltration you are using. Obviously if you're using more filtration manual tankmates, you won't have to change it that often. The other hand, you may have to change some of the filtration more often because it gets clogged up. Only ever rinse biological filtration out in existing tank water.

I hope I haven't confused you

Just got a new Oscar yesterday, When I opened the bag (after letting it sit in the tank for a while) The fish just sunk down to the bottom on its side and just sits there.


This happened to me once when i bought one oscar, whenever i have bought more than one or added a new oscar to a tank with some in this didnt happen.

I am going to stick my neck out and say this only happens if you buy one oscar and put it in a tank without other oscars.

I have a 60 gal Aqua-tech filter.

It has a cartridge which contains carbon and a filter (all in one), this can be replaced.

It also has a mesh bio filter which should never be replaced. I'm assuming this is where the bacteria lives.

What converts the Ammonia to Nitrite (and then to Nitrate) the carbon or the bacteria?

I was under the assumption that the carbon did it, I think thats where I was wrong.

I clean my filter every 6 weeks. Clean the sponge (mechanical) out thoroughly, rinse the ceramic balls (or little rocks or hollow tubes) in tank water that you have taken out

When you do your weekly water change do 50%

I dont know the filter you are taking about however from what you say the mesh bio filter is where all the good bacteria are. This bacteria is what converts ammonia to nitrite and then to nitrate. You keep nitrate down by doing water changes

Carbon is good for removing medication and also is supposed to keep the water crystal clear. I dont use carbon, i dont think it is necessary (its also expensive) because if you maintain your tank well your water will be clear anyway. If you use carbon it needs to be replaced very regular (every 6 weeks i think) or it starts to put back into the tank what it has taken out.
