jesus christ, soooo awesome....best tank setup i've ever seen
looks better than the piranha tank at my local zoo, congratz on that awesome tank
love the white sand and the plants as well as the trees, i guess i'll use your layout as an inspiration for my tank
i'm not sure if i should go with white or dark substrate...white looks better but black brings out the piranha's colors more...
maybe i'll go with white sand and peat filter, for a rio-negro-style aquarium
although i gotta say, i'd like some real plants on the bottom and sand + plants = fail, right?
i guess i'll use some rootless stuff like elodea and some floating plants
