slipshodman created the topic: Pairing Oscars, Grow out or not ?

Hi Guys and Gals,

So like many of us i assume i would like to eventually breed Oscars, Breeding fish for fun (not profit) i find just a really enjoyable experience, watching their behavior and parenting skills i find fascinating
Although i must be honest i have not been particularly successful to date (i have never tried breeding Oscars before)

Anyway, so my question is what is the best way to find a breeding pair

Should i look at getting a larger group of juveniles and growing them out to see who pairs off ?
Is it obvious when they pair like a lot of other species.

Any suggestions here would be appreciated

I never tried breading Oscar's and probably never will because if they start breading succefully then we may come to have hundreds of fries and juveniles and no room for them. LFS may get some but what they pay and the amount that may be sold would still be too short for the necessity.

However in some online articles it's referred the purchase of 6 from 2 or 3 different origins to guarantee a compatible pair as the grow up.

To be perfectly honest with you I think it would be a mistake to actually purposely breed Oscars if you don't have a plan of what to do with the babies. We had a member a few years ago whose Oscars would breed every two or three weeks. She would literally end up with hundreds of babies that nearly always died because she didn't have any facilities to deal with them.

However, to answer your question, the best way to get a breeding pair is to buy several Oscars and keep them together until they become sexually mature. I did this back in 2006/7 and even though I had eight Oscars I never actually got myself a proper breathing pair. Several of the Oscars would lay eggs, but nothing ever came of it. When I did I started off with a 125 gallon tank that had already put in the plans of having a 350 gallon aquarium installed. So by the time the Oscars had reached 5 inches I have moved them into the big aquarium. Even though 350 gallons isn't really big enough for that amount of Oscars, I also had an extremely large sum filter so was able to keep on top of the water conditions. This is something you have to consider, have you got the facilities to keep all these Oscars healthy for what will probably be more than 12 months?

I may not always be right, but I am always the BOSS :-)

I tried this many years ago. Total fail due to the slow maturity rate of Oscars. Not to be confused with growth rate. A foot long Oscar can still not be sexually mature. Trying this in even a normally large 180g will fail due to space restrictions, aggression and water quality struggles.

Thanks for the comments guys,

So, just thinking out loud

Currently I have the 600ltr (6x2x2, currently running 2 canister, 1x2700Ltr p/h mechanical filter mainly with bio, 1x1200 ltr p/h bio filter), which would be a grow out whilst trying to pair them (start with 6 juveniles and see how i go), they can stay in the 6x2x2 with my peacocks and pleco's for the first couple of months (no more than 3) while i prepare other tanks for the Africans.
If they mature at about 12-18 months old i am guessing size would be approx 8-10 inch so i would have to be really on top of it as tank size would be absolutely maxed in the last few months pairing them. (please advise if incorrect Age/maturity etc)

Then the pair would call the 300 ltr (4x2x2) home for breeding, i have spare tanks ranging from 100 ltr to 300 ltr which would be set up for staged grow out of fry in my garage, i also have access to a couple of IBC's (not sure what you call them in the states, but these are 1000ltr square tubs basically) that can also be set up for the grow out conditions, and in a real pinch i have a pond set up outside that through summer,autumn & spring could cater for some, multiple stage ponds but the 2 main are 1000 ltr and 2000 ltr approx.

Believe it or not in Aus its not that easy to get little Oscars except juvies at the local aquarium store, not many people breed them here at all, not that my aim would be to make any money, it would be a hobby really nothing more, i assume the local stores get imports really cheap from Asia (big fish farms).

So there would be a market for sale to Local s stores and via local clubs/forums etc but as i said, the aim would not to be making money, just the hobby and if it covered some costs all the better.

So i wouldn't be going in totally blind/unprepared, still not even sure if i will do it at all, but it is good to throw thoughts around with like minded people to get their knowledge/experience & advice.

I suppose you always think a bit bigger then you actually end up doing, well in my case i do, but there wouldn't be much standing in my way of getting this up and running ...hmm... food for thought

Please comment, question, tell me i am a clown :laugh: :laugh: :laugh: , whatever, i would love to hear your thoughts

Thanks all

They mature at a minimum 18 months, on average closer to 2 yrs. Could be 14ins by then. 8-10 would be small. Sexually mature doesnt mean egg production. I have a 5yr old female, very big girl. Never laid eggs. 300L is 75 US gals, while a 4x2x2 is 120 USg. Neither is suitable for a pair. The 120 is bottom end on volume, but short on living space. I have another pair in a 6x2x2, a standard 180 US g. Like 720L. I couldnt imagine 4 more in there, or plecos, cats etc. Tank is full by my standards. Even the 2000L pond is about 500 US g. Still not overly big for a pack of fish that can weigh 3lbs.Gobs of filtration, tons of water changes and sheer determination you may pull something off. Best I can offer you is GOOD LUCK!
