sorry, yes it is aq. pharmaceuticals...and if you print out an online price, i believe that petsmart will price match which could save you a little bit of cash.
that would be fine, sand seems to be all the rage lately. Most people seem to either like tahitian moon sand(dark/black), or pool filter sand (super cheap/light).
most tetras' natural environment has a sandy, silty bottom.
my next tank is going to be south american style... and I think I'm going sand. I just can't decide whether to use dark or light sand. I've been consideirng mixing it 50/50, but I don't know what that will really look like.
