After further disscussion, the tank is indeed going to be a planted community tank with a Fluorite substrate..
Fish I'm considering are as follows:
Gold Rams
Apistogramma caucautoides
cardinal tetras
angelfish
various cories
some sort of 6" ish pleco.. I'd like to do a gold nugget, but they get too big.. suggestions?
I'm open to other fish ideas, preferrably in keeping with the South American theme. I don't think the pleco is SA, but ohwell.. Puma's list from earlier is a good place to start, and I'm looking in to all of the ones he listed.
As for plants, I've always been a fan of the Amano style tanks. C02 is not going to be used though, nor is any sort of hi wattage lighting. Simple NO lighting, POSSIBLEY some CF or VHO.. So I need some medium-low light plant suggestions. Nothing ornate or difficult to keep, just simple, hardy, bright green foliage to contrast well with the dark brown Fluorite and the fish... The fish are the focus, not the plants. For now at least.
Filtration will be either a Fluval or another canister filter.. I've been away from fish keeping for awhile now, and I'm not familiar with current hardware.. Whatever I get, it will have a surface skimmer.. I have several powerheads, but I don't know if they'll work with a planted tank. Rather powerful, so they might blow things around too much. For a heater, I've got a couple 100w Ebo-Jagers to use. I'm also planning to use a sand filter, for supplemental biological filtration. Sand filters are bad for building up nitrates, which should actually be good for the plants..
