seems like you need to look at all types of tanks and see
wiht one seems better to you. some of MY favorites are
south american tanks wiht tetras, angels, discus, and plecos.
these usually havelots of plants and "root" looking driftwood
pieces. they are really colorful and full of live.
Asian biotopes are really kool too, they usually have pebbles
for substrate and skinnypieces of driftwood, as well as lots
of long plants, they usually have betta's and otehr asian
born fish.
you could also do a cichlid tank. but i know NOTHING about them,
hah
or maybe even a discus tank! those are always erally pretty,
but they requiere EXCELLENT water conditions and alot of plants.
ahah
good luck wiht your tank.
