So I have cycled my 75G and added the O's in the tank. So far they seem very happy. Agent Orange is about 6 inches and Night Owl is about 4 inches. I was wondering if you guys thought I had too much stuff in my tank or if I should move some things around to make better shelters for the Oscars, Pleco, and Raphael Catfish. I know it is wrong, but I was an impulse buyer of the beauty of the O's, and they did not last long in the 20G tank so that is why I've upgraded so quickly. I am learning, taking suggestions, any and all critiques are accepted!

It is my understanding that this aggressive behavior is due to a territorial issue. Now I did not have too much time to explain the extent of my situation. Being an impulsive buyer I went and purchased a pair that was with two Jack Dempseys. The reason they were aggressive is because I did not do my research and thought it would be fine to hold them in a 20 gallon tank. WRONG. I have had them for about a month, the first two weeks they were in the 20 gallon tank and this is when I started noticing aggressive behavior. I already knew from reading that I was going to need a minimum of a 75 Gallon tank for JUST two oscars. I now have a properly cycled 75 gallon tank and the Oscars have been in it for two weeks just about. My chemical levels are all in the clear due to the filtration I chose and the water changes weekly that I do so far. My end goal is to get a 180 Gallon tank so that I can have them happy.

I have read some articles on oscars even being territorial in an 800 gallon tank, and many success stories of them being kept in a 75 Gallon no problem. I do have the Pleco and Raphael Catfish in there and like I said before do plan on getting a 180 Gallon tank eventually. I do take your advice as a professional opinion, all of you, If they do breed I can take them to the local fish retailer, I do want to keep two oscars, and I do want them to be a Male female or female female because the chance of survival is higher than a male male (alot higher from what I have read).

Like I said before the details about the 20 gallon tank were not mentioned in my previous post and they are now properly housed so I hope the aggression goes to a minimum. Here are some pictures of the fish and the tank setup, let me know if you think its to cluttered or suggestions for change in the layout because i know oscars like their own little "dog house" lol.

This is my tank setup, personally I would like some advice on if you guys think I should move things around in there or take things out.



This is the Aqua Clear 110 filter that uses filter media. I was contemplating on switching the ceramic rings out for small lava rock. What do you guys think?



This is the Sunsun HW-302 3 stage. I have the bottom tray with a course, medium, and fine filter. The second tray is Ceramic Rings, and the top tray is Carbon in a bag. I was wondering if you guys think I should ditch the carbon and replace it with Lava Rock.



This is Agent Orange. He or she is the 6 inch Oscar. He was also the bully in the 20 gallon ( I know i messed up)



This is Night Owl. He or she was bitten a few times in the 20 gallon tank by Agent Orange, but since its been in the 75 Gallon he is recovering nicely.



So here is all of the Information on my setup, Let me know what you guys think! And thank you for the replies already!

Welcome to OFL.

Your tank is overstocked. A 75 gallon tank is good for one adult Oscar.

The best thing you can do, if you care about your fish, is to rehome all but one Oscar.

Other than that, your tank looks good. Very decorative, and you have a skull!

Nobody is going to blow sunshine up your ass on this site regarding stocking. You are overstocked....period.

Do the right thing, and feel free to ask all the questions you want. We all help each other to do the right thing here.

You are totally right there, and I don't like smoke being blown up my ass :) Thanks for the good advice. I already know this, and as I said in my post I plan on moving them to a 180 Gallon tank within a year. I bought them as a pair and I do not want to separate them. So I feel you there, but what would your suggestion be on the length of time allowed in the 75 gallon. I mean my filtration system is more then enough (not sure if you saw that part). My chem readings are golden. The Pleco and Raphael are small and are constantly Hiding. I have done as much research as I can, and know they grow fast, I know they need at-least 100G for two, plus I have the Pleco and Raphael. As long as I keep my readings of Nitrate Nitrite in the clear I should be alright for a while right?

By the way I am constantly on Craigslist looking for a Larger Tank. Do not worry, these fish will be taken care of. I do care about them, I just cant let myself get rid of one because i'm attached already!
Thanks for the comments on the tank, any suggestions for the layout? Or do you think it is suitable for the O's, im just worried they will run into stuff lol.

Thanks again!

Good for you wanting to do the right thing. You should get that 180 right away. There getting up there in size and yes they grow fast. That 75 isn't big enough for the size of the fish and the numbers now. They will start to stunt. I would also look for something bigger such as 200+ to keep them all together. 100 gallons isn't big enough for 2 oscars. 125 gallon 6 foot would be as small as you want to go for 2.

Tank looks great.

But yeah get that 180 asap. Although you have good filtration... Nitrates are produced as a byproduct of the cycle. The only way to remove them is water changes. No amount of filtration will change this and you'll want to keep them under 20ppm

"I already knew from reading that I was going to need a minimum of a 75 Gallon tank for JUST two oscars. "

Where did you read this? No offense, but that's so erroneous as to be laughable. 75GL aquarium is sufficient for one Oscar only. To overcrowd the aquarium further for any length of time is to subject your fish to poor water quality, regardless of filtration, which will lead to stunting, stress, & exponentially increase risk of disease, up to & including HITH/LLE.

Oscars are waste producing machines, as are plecos. Fish constantly respirate & urinate in the water column, which constantly adds ammonia. Add to that defecating & the mess they make when they eat, & you have a "perfect storm" for poor water quality, regardless of filtration.

What exactly are your readings for ammonia, nitrite, nitrate? If you used test strips, discount those readings.....test strips are garbage & beyond inaccurate.

How long did you cycle these filters (you don't cycle the tank)...they look brand new. Just FYI, it takes a minimum of 10 weeks to culture a mature biological filter.

I would also more than strongly recommend you do daily partial water changes on the order of 75%, vacuuming the gravel each time.

I would remove almost all decoration to allow for maximum aquarium space.

If you can't obtain that 180GL in a week or two, you will have some hard choices to make...this is not a set-up that will last long.

THOSE WHO REFUSE KNOWLEDGE ARE DOOMED TO FAIL.

WATER CHANGES ARE THE LIFEBLOOD OF THIS HOBBY. IF YOU DON'T BELIEVE SO OR SIMPLY DON'T FEEL LIKE DOING THEM, RE-HOME YOUR FISH, SELL YOUR AQUARIUM & FIND ANOTHER HOBBY, AS YOU WILL FAIL UTTERLY, COMPLETELY, & MISERABLY.

Thanks for the input as I am sure you are an experienced Oscar keeper. This is why I came to the forum is to get this advice. As for the can filter it has been running for about a month. I had it cycling in the 20 gallon tank as it was the first piece to the tank addition after I realized my mistake. The AC110 has only been running for 2 weeks.

I understand O's are very messy fish, and this is likely the reason why it is "not acceptable" to keep 2 in a 75 Gallon.

I'm guilty of using the test strips, are there any cheap good test kits on the market that you know of? Are they easy to read? I just do not understand how that much water is not enough space for these guys i guess. They can grow quite large i understand and around 12 inches is average no? So it comes down to a matter of territory for the Oscars assuming my water is in spectacular shape i am guessing.

I have been doing 50% water changes every other day for two weeks and with the test strips they say its all good in the water, but I need these other testing supplies.

I will take your advice and try to re home one of the Oscars if I cant pick up a 180 gallon tank so at least one of them can live a happy life.

As for now, I can remove most of the decorations to save space. I like the basic look better anyway.

Thanks again for the input, and I know you hate to hear noobs talk about this kind of thing, but its a work in progress. I can promise that.

get the api master test kit. if you get it on ebay or amazon it'll only be about 20 bucks... but it'll run u around 60 at the local fish store

the reason that the 75 isnt big enough is because it'll be impossible to keep the nitrates at a safe level as the fish get bigger. youd possible have more aggression issues as well

OP, good for you for deciding to rehome one Oscar. If I understand you correctly, you still have an Oscar, a Pleco, and a Raphael Catfish in a 75 gallon tank? Hate to tell you, but that's still way overstocked for a 75 gallon. Common plecos get huge and are poop machines.
