Keeping Oscars isn't challenging, in fact they are one of the easiest fish to look after as long as you provide them with the correct living environment.
I agree with you there...what I meant with "challenge" though was...they need bigger tank than most fish, need good filter system seeing as they are messier than most, etc. So "sorting" out a way to run a sump would be considered a challenge giving the fact that I would have to build/modify a few things(mind you...paying ZAR 9000 for two Eheims is a challenge in its own

)

In my opinion the amount of work involved in installing a sump on your aquarium far outweighs the actual benefit of having one in the first place.
You are prolly right...but wouldn't it feel better building something and stand in awe after everything is done...compared to simply buying something and throwing it into your tank? Debatable I reckon...
