I hate ornaments in tanks (terracotta pots for breeding don't count) and prefer the natural look in decor and colour. Also dislike unnatural colours in gravel - eg blue (no offence to those who like it, it is my personal opinion only)
I like a tank with lots of smaller fish, like barbs and tetras, rather than a few large ones.
Currently down to one tropical community with tetras, barbs, gouramis, hoplos and bristlenoses.
