Re: possible to have too many bottom dwellers?

I disagree. A group of six of either species would be ideal. The loaches and cories are not at all aggressive fish, and there won't be any fights between them. They do a *lot* better in groups.
Since it is a 30g tall tank though, just in terms of general space I think only one type of bottom dweller that needs a school would be appropriate.
If you're just using a bowl for some sand, you definitely don't need a ton of it, but you can buy a big bag of play sand from Home Depot for about $4. Just be sure to rinse it really, really well before putting it in the tank or it'll look like you filled the tank with milk. Play sand is perfectly safe for your fish and is a heck of a lot cheaper than sand sold specifically for aquarium use.
