What is going to happen

Okay, I set up a classroom tank, I purchased a jack, an Oscar, and a green terror. They are all 1.5 inches except the oscar is 2. They are currently in a 35 growing out and will go into a 90. What should I expect behaviorally and can I put a bristle nose in with them
Thanks in advance for the feedback

Aggression. The bristle nose will be fine so long as it doesn't fit in anyone's mouth.

Thanks for the answer. By aggression do you mean territorial scrapping or bloody dismemberment?

Every fish is a little different, can't predict it. Eventually I'd expect the oscar to get shredded by one of the others, but that's just the law of averages.

A 90 is not going to be big enough for the Oscar alone imo. The gt and JD will likely be a problem quite soon imo.

I don't think this kind of tank works at all.

Jd in my experience are though. Oscar grow faster then the other 2 and will eat anything that fits in its mouth including a jd and green terror. The oscar might get picked at since he is the least aggressive. I would not recommend a bristlenose plecostomus since they are slow growers and can potentially be a choking hazard for the Oscar

Thanks for the input everyone, sounds like I may need two classroom tanks. What kind of growth rates am I looking at?

Oscars can grow up to a inch or so a month for the first 6 months. Jack Dempsey are slow growing aggressive fish it'll probably pack on about 3 inch a year. They can reach 10 inch or so but your looking at a 3 or 4 year old +. Green terros grow about half that of a Oscar around .5 inch a month for the first year of life after that they slow down quite a bit.

I've had Oscar hit around 10-12 inch in a year with proper care food and water parameters

Thanks everyone, I was planning the upgrade for Christmas break. I hope I haven't under estimated
