i know this feeling well!
my oscar has a staple diet of Tetra Doromin cichlid sticks,( twice a day) then once a week i chop up some prawn for him ( freezer section at tescos) then he has peas -when i think i wont be wasting my time trying to get them to eat them ( stubborn bugga he is) so thats probably about once a week too, i would advise against feeding goldfish,and beefheart the goldfish probably have more nasties that goodness, and beefheart is very fatty for them ( ok as a treat in very small portions, but they dont
need it) mine will also eat cod fishfingers.. yes i take the breadcrumbs off for him first
and just about anything else edible
( choc donuts too)
be carefull were feeding is concerned as they do have this lovely habit of making you feel like you`re starving them.. wagging,dancing etc... that look, anyway, all you will achive from over feeding is an oscar that wont live out his 10 yrs as healthy as he should- they need excellent filtration- the bigger the better.
i have my single 12inch oscar in a 300l...and its not ideal, but this is only a recent thing as hes getting old and less active, of course he has plenty of room, but they are strong swimmers and will appreciate lots of roon
the personalities on these fish are wonderful.. they smile and give dirty looks ( not literally .. i havent lost the plot.. yet) but i bought my very first 2 as an impulse buy ( my bad) and have had several since them,i couldnt be without one..i think its a fantastic choice youve made, just make sure you have what you need equipment wise as despite what people think they are not as tough as old boots when it comes to ammonia,cramped conditions,poor diets etc etc.
wish you all the best should you decide to go ahead
