Oh so you got two. Let me be the first one to mention that 240 l will be too small for them both in the long run, would recommend at least 400 l, bigger is better.
About your Oscars, it is normal for them to sulk as you said already, so they might be adjusting still. I assume you cycled your tank before putting the Oscars in there? And are they eating yet? If not, did you remove the uneaten food again?
With them being messy fish, water quality is likely to decrease anyway in a small tank like 125 l, so I'd do regular tests and water changes and make sure ammonia and nitrites are zero, and nitrates not too high. Sorry if you know and do all that anyway already, but thought I'd mention.
If they're just being shy still and everything else is fine, I'd expect them to come around and be more active on their own in some days.
Whoops, forgot about the photos. Many here just upload their photos to
photobucket
and link to them here. Else if you have no program to resize pics, there are simple freeware ones like
Irfanview
that make it very easy to do that, should be no more than 400px wide or high I think, and less than 50kb.
