I've been browsing some other sites looking at Oscar 'friendly' fish and someone suggested Convicts and I like the look of these fish.
Could I start my 3foot tank off as something like 2 Clown Loaches and a couple of Convicts with a med sized catfish? They will not get to full size in this tank, it's only gonna be thier home for about 3 - 5 months. Car registration and insurance time at the moment

.
Any other suggestions?
The 3 foot tank will be a decorative tropical tank in the rumpus room (basically our entertaining room) once I get the big tank for Oscars in my loungeroom.
