I have 2 oscars in a 65 gal tank for about 3 months now along with a small red tail catfish who will eventually move to my 300 gal stingray tank but my oscars were cool and all until a few days ago when i turned on the lights to see that there eyes had changed colors, not permantly but looked pissed and were pushing each other lip locking and shaking. They are both about 8-9 inches. Should i seperate or expect babies??Any help is greatly appricated

I think you need more than 300 gallon for a red tailed catfish, they can reach four feet in the wild :lol:

Okay, 65 gallons isn't really big enough for two Oscars unfortunately.

Difficult to say whether they are sexually mature. How old are they? If they aren't at the moment, I don't think it will be too long before they are.. The behaviour that you have described can be a sign of the aggression and a breeding ritual alike. What you should do is observe the Oscars in between this behaviour. Do they look like they are not getting on? Do they avoid each other all the time? When they do fight, are they causing each other any physical damage? If the answer is no to all these questions then don't separate them, just wait and see what happens. You may or may not get eggs before too long. However, there is a possibility you have two males or even two females. Unfortunately you won't know until you see eggs being laid. Where they're going through this behaviour, have a look at their undersides, see it as anything protruding. Sometimes the male does get aroused, if that's the right way to put it. He will have little spike sticking out of him.

If your Oscars fight constantly and are always causing each other injury, then I would separate them

They are each almost a year old and 8-10 inches. Ones underside is actually almost rounded by the anal fins. The other one dose have a "spike" but it could be a fin. They seem fine otherwise and rub up on each other when they arent doing this. I guess i will just have to wait and see. Oh if the red tail does outgrow the 300 gal i guess he would make a great meal, just kiddin. If he does make it that long ill buy him a cheap plastic pool with large footprint but thats a long ways away my friends. Does water temp create aggression, its been hot in the northeast and my tanks been unusally hot these last few days.

I have heard that red tail catfish are great on the barbecue :lol:

No, water on the warmer side shouldn't cause aggression, never had a problem here and occasionally my water gets to around 31°C on really scorching days.

The sexual organs won't come out unless they are actually going to lay eggs, or sometimes during the breeding ritual. The spike you are referring to does sound very much like parts of the Oscars fin, I've seen that before and sometimes at a quick glance, it does look like the male sexual organ.

If there are going to start breeding, you will notice both of them cleaning a flat surface vigorously. They will do it for a long time. If you want to encourage them, put a flat piece of slate in the tank. This is perfect for them to lay eggs on

Red tail cats get massive(4ft+) and they grow quick. Go to the london aquarium by the millennium wheel to see just how big. They have a massive tank full of them there. Red tailed cats also have very large mouths so watch it if they are in with fish that are about half its size. I would get rid of it before it gets too big and difficult to find a home for. On the other hand they can be trained to be tame and will eat out of the hand. I only know what i have been told tho- i have no personal experience


If your oscars are not damaging each other then i would leave them and see what happens

Hey dont be so pessimistic about red tails. I am blessed to eventually have space for him if need be. He actually is my fav fish other than my oscars of course, and this includes motoro stingrays. He eats frozen silversides outta my hand. Has a head like a hammerhead shark about 9inches long and heavy like a bag stones. Def not for amatuers but if you are willing to eventually house a monster why not. Just think how great it would look to have a huge redtail in your house, great convo piece. Im from New York so I cannt make it london but i wish i could. Great web site very imformative.

Nice to have you on board, hope you'll stick around on the site, I'm sure you have lots to contribute.

Do you reckon you have got a tank big enough for this red tail?

Absolutley not. But if need be if he makes it that far with proper care I'd just get a cheap swimming pool with large footprint like a kids pool 500-600 gal and put him in. My office actually shed that was converted to office he'd be great hopefully i dont lose any fingers though. Hey off the red tail talk how often do you guys feed mature oscars, every other day daily, weekly? just wondering

I don't think there's anything set in stone that says how often you should feed an adult Oscar. However, from experience, I think that an adult Oscar should be fed every other day. If you've got other fish that get fed every day then the chances are he will get a feed most days. When Oscars reach adulthood they really don't need as much food. If you do feed sparingly, you do reduce the chances of the Oscar stopping eating. This is such a common occurrence. I often get asked by people why their Oscar has stopped eating. I think it's best to keep them more in the hungry side, they're more likely to accept a wider variety of food. One day a week you could give them a really good feed if you want, but all the other days, just feed them sparingly. It would be much better for their health in the long run. Overfeeding fish is just not healthy for them
