ok so next year i will be setting up an arow tank. is a 8x2x2 good?how many arow can i have in there? by chinese feng sui, i can only keep odd numbers, so yeah. also what tank mates could i add? i want to setup either an asian teme or an amazon theme. does any1 else have any cool setups for an arow?wat fish would i have in each setup that can live their permanantely? also the silv aroz at hacienda hts aquarium has them but they have orange tails is this good or bad? they look just like silv arows but with orange tail and same body shape.
