Sophia that thought did cross my mind but I have terribly bad aquascaping luck with anything over 100 litres :-? I've read that no matter how well I scape it, Oscars will rearrange it given the chance. I want to go really rock heavy, got a couple of solid pieces of alpine cobble with the tank for main rocks, will buy some more from 20cm down to 20mm pebbles with a sand base. I might give java fern a go but the fish I want don't usually play nice with plants :nilly:
