... so that's a lot of bottom dwellers. Is it possible to have too many? The tank is a 30h (i.e. it has exactly the same floor space of a 20h -24x12) so it might get crowded down there pretty quickly.

Is it possible to overstock one "level" of the tank even if you're not overstocking in terms of total gallons?
way too many bottom feeders. stick with one type. and even with one type. any more than 3 would be way too much for a 30g. it will become a territorial battle and some will starve to death. if you have more than one type. there will be fights. and the dominant one will get the food leaving the other to once again starve.

I'll have to refer you to that guy who says I have to keep a minimum of six kuhli loaches if I want any loaches at all... you two can argue about it and let me know who wins. :)

I have about 10 fish in the 30g so far - when I feed them, they all just eat happily, nobody bullies anybody else - I think it depends on the species... I'm trying to be pretty careful (although I did just put a ptenopoma acutirostre into a community tank, he's still practically a fry - I'll be keeping my eye on him to see how he does with other fish...)

1 Cocker Spaniel - Zoey
1 Mudskipper - Pangea
3 Bettas - Mars, Venus & Neptune

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.

Thanks for the home depot suggestion! I was about to but a little
5 pound bag for $4 from a local store - which is still about 40% less than what petsmart charges for freshwater-safe sand.

I do want a lot, because I also want to use sand as the substrate in my 15g...
