300 gallon oscar pond?

  • We are currently upgrading MFK. thanks! -neo
I think it could probably work, but would be pretty high maintenance when the fish get big. One oscar can do a pretty good job of fouling a 75g. Like cichlidfish cichlidfish said, filtration will be a big component of success. A high capacity sump system would be the best way to go. It could handle the bio and add some water volume.

Yeah lots of filtration.
IMO if looking for pairs, then it's best to buy 6-8 because oscars can't be visually sexed. Grow them out, once you get pairs remove the ones that haven't paired. Odds are there will be only a few pair IMO. Not sure if the goal is to get pairs.

Obtaining a pair would be the only reason I would put 6 or more together, still no guarantee but a good chance. I guess I assumed that was the goal.
 
Not really a goal, would be nice to just have a decent size school of oscars, maybe rescue them since people get them and get rid of them so easy. I just know there are chances to them pairing off so I didn't know the temperament if they do pair off. It's a metal trough so more like a pond less like a tank

just want to point out as an aside - oscars are not a schooling fish, and they will never exhibit schooling behaviour no matter how many are placed together. They do not get lonely, and do not particularly desire to be surrounded by other fish.

Keeping a bunch together can work, but it will depend on the personalities of the fish - they are individuals and they will each have their own temperament. They don't seek safety in numbers (oscar ain't scared of sh*t) and you should be prepared (and capable/ready) to separate them if needed. (which can happen suddenly)

just wanted to add that in. You may have just meant school as in a "group of fish" but I took it by its proper meaning just in case. We keep a pair of big ol' albino tiger oscars together at work and they're lovely. It is difficult to keep junior staff from slipping them crickets on the sly as they enjoy them so very much, despite that they're banned from live crickets due to the risk of parasites.
