after my oscar and green terror fight I decided to move the green terror out of my red oscars aquarium. my lfs has had some big oscars for about 3 months now ,2 tigers, one 16" and one 14" in a 40 gallon. I want to get one for a tankmate for my oscar. on the 75 gallon aquarium there are 2 emperor 400's and every 2 week 30% water changes. the oscar in there now is about 10 inches and the one that I would like to get is about 14 inches long. so I was wondering could they stay in there for about 2 or 3 months until I have enough to buy a larger aquarium?

You could probably get away with two in a 75 if they grew up together. You would have to do a lot of water changes. I would be concerned about putting two full grown strangers in together. The one you already have has probably already claimed the tank as his territory. If you put a new on it, they might fight quite a bit. I would think a while before adding another adult.

I was thinking that he had alredy claimed his territory since he tried to kill a newly introduced pleco. thanks for the reply. I don't think I am going to get it since they might not get along.

I have a three month old oscar that's grown to nearly six inches, I think he might be lonely and I want to buy him a tank mate. I did some research and I was considering a jurupari earth eater. I know on average they don't reach the size of an oscar but I think that it would be a beautiful addition to the aquarium. does anyone have experience with earth eaters? would this be a good roommate situation? any other comments related would be appreciated. I just want horus to be happy.

Before we suggest any tankmates, what is the size of the tank your oscar is in? Once we know that we'll know how much room you have for more fish and suitable tankmate choices,

I have a tiger oscar thats about 13 inches in with a 5 inch jurapari and they get along just fine with no fighting. to keep these fish together you would need an aquarium of atleast 75 gallons.

I second that motion, you're going to need plenty of room for your Oscar, they routinely get to be 7-8 inches before they are 18 months old, and grow fast (at 1"-1.5" per month). 55g would probably be the minimum, and some people will tell you even that isn't enough room.

IME, When choosing tankmates, taller fish are better than longer fish, and Oscars adapt to tankmates better when younger -- after a certain point, they see anything added to the tank as food. If your guy is more than 4-5" or so, it's best to leave him alone, OR find a fish that's too tall for him to swallow.

I kept a 5" Juruapari (and silver dollars) in a 125g with my Oscar until he died (by floor) at around 7-8" with few problems, although both were regularly harrassed. I added the dollars when my guy was about 3" and the Juru when he was between 5 and 6 inches (after he ate a 4" clown loach!). Both the Juru and the dollars ate up the food the oscar missed and helped keep the tank reasonably clean.

The think with Juruparis is this: they like to sift and are happiest with at least part of the tank set aside to sand, and they are sensitive to nitrate.

Good luck!

Here is my setup:

75 gallon long (5 feet long x 1.5 feet wide X 16" tall):

1 Albino Oscar (12" including tail)
1 Synodontis angelicus (7")

2 eheim 2126 filters and 1 Maxi-jet 1200 w/weekly water changes.

My Oscar got along with tankmates until he was about 1 year old, then he turned on them. Now he just lives with a catfish that is nocturnal so there isn't any fighting. Also, the synodontis is pretty tough.

I understand that when Oscars are little there is great temptation to add more fish, but as soon as your O gets bigger (which won't take very long), I don't think you will be dissappointed. I would go no smaller then a 75 gallon for one Oscar. They need the space to swim. Also a long tank is much better then a tall tank when it comes to Oscars. They are also sensitive to poor water conditions and are susceptible to HITH.

if you do take out the blood parrot, convicts in my experience are usually good tankmates for oscars.

theyre quick (to get out of your O's way), somewhat aggressive, and grow to a good size.

goodluck

Yeah, a convict might work but if there are two cichlids in a tank, they will probably fight.
