Most entertaining way to give larger fish ""feeders"?

[Ottobon]

I have been taking care of our baby Oscars at work and on one of the many trips to the petstore i was able to intereact with some adult Oscars, and to my suprise their 10x more aggressive then i ever thought (deffinitely more agressive then our little babies.) The middle age 4 inch Oscars where jumping out of the tank and hanging on to my finger in attempt to cure their hunger, scary. So now i know that the fish we have at work are going to grow up and be crazy as hell i thought why not allow them to get some of the crazy out so that they don't end up having pent-up energy like indoor house cats do.

I'm thinking about giving them feeder fish, but i feel just throwing the little fish in to get gobbled up is a unfair and maybe even a little perverse, so i was wondering if there is any sense in buying a few little areas of shelter for the little ones so the smarter guppies will stand a chance and at least not straight away get gobbled up by the bigger fish.

I do expect the Oscars to eventually catch the feeder fish, but in a perfect world I'd love for the feeders to atleast have a very minute chance of somehow surviving much longer then otherwise capable, I'd also like to force the Oscars to hone their hunting skills rather then just being literally spoon fed. So basically is it possible to set-up a fish tank for a decent game of cat and mouse?

That is a tough one, usually if you do it that way the other fish will just die of stress, the only way to make it fun is to give them a lot of feeder fish every few days.

How about slowly putting more and more dangerous animals into the tank, rather than guppies

You know you can feed oscars beef? Burgers? Ok, but boring. How about doing that jurassic park style?

I have had several different Oscars. I never really fed them too many fish (only one pair) because it was just too messy, plus alot of "feeder" fish are usually disease carriers. They usually get alot more aggressive when you feed them live fish too.

So I always just stick to pellets

yeah maybe i'll just do that, if the fish don't end up aggressive already then why prevoke it? Just thought it would be a entertaining spectator sport for my boss as shes goofy like that. I'm planning on getting her a trail membership at a gun-club because she wont stop talking about how cool she thinks snipers are (this is from a 45-50 something Vietnamese refugee none the less)

It's too mean putting little guys in, it avoids casuing what you really want to happen. THIS.
