Thanks for the feedback everyone. :] Definitely helpful!
Byron, I am unsure (and torn), to be honest. My first thought was to get the tank running and cycled.
My other tank is a 20 gallon tall planted with black CaribSea sand and 2 golden panda mollies, 1 sail-fin lyre-tail molly, 1 dalmatian lyretail molly, 1 dwarf gourami, and three corydoras (albino, julii, emerald). They all play very well together and the Dwarf Gourami keeps the population down courtesy of two very healthy, active breeding molly pairs.
With this tank I wanted something a bit more exotic and dynamic - perhaps full of small peaceful schooling fish, colorful barbs and small sharks, an array of semi-aggressive colorful cichlids, or two larger tiger oscars and a pleco. Whatever I plan on going with, the first fish I plan on getting is a bottom/algae feeder - I've been reading about plecos. Some species of pleco can grow giant, however the ones I've been reading up on (Gold Nugget and Tiger) only reach 6-8 inches. They're really charming creatures (I also love corydoras - soft spots for bottom feeders I guess). Any thoughts on the perfect bottom feeder (or feeders) for a 45 gallon tank?
The decorations are natural brown river rocks, a couple silk plants, and a really magnificent piece of underwater root (plastic). Great places to hide and many places to school and swim about.
I'm overwhelmed with possibilities.
