Hi there,

Congratulations on your fishtank

Unfortunately, angelfish are too big for this tank. Angels can grow to be 5 inches wide and 7 inches tall; they need a lot of room. Also, while not schoolers per se, angelfish are very social fish and are happiest when they have other angels around.

Because of the dimensions of the tank, you can not have too many fish. Fish with large footprints (total surface area) can accomodate more fish because there is more ground space, and because it allows for more gas exchange.

But you still have lots of choices.

First of all, have you cycled a tank before? In the wild, and in established tanks, there are nitrifying bacteria that break down toxic ammonia from fish waste and excess food into less toxic nitrates. In a brand new tank, these bacteria don't exist, so any fish in the tank will produce ammonia, which, not being broken down by bacteria, will kill or weaken the fish. So, it is vital to cycle your tank.
There are a few methods. Do you have access to an established tank? These bacteria live in the gravel and in the filter cartridge, so if you can get some from another tank, you can put the bacteria right into your tank (don't let the gravel or filter cartridge dry out). If you do this, in a day or two, your tank will beready for fish.
Another way is to get Bio-Spira. It is the actual live bacteria in a little pouch, and your tank will instantly be ready for fish.http://fishstoretn.com/bio_spira.html

Other methods, which include putting a source of ammonia in the tank and letting the bacteria build up on its own, or putting a fish in and letting the fish produce ammonia (which borders on animal cruelty, because the fish will suffer from the ammonia in the tank), take 2 to 6 weeks before your tank is ready. If you rush that, any fish you buy may die, so try one of the instant methods I mentioned above (bio-spira or gravel from another tank)

When stocking a tank, you have to look at the levels of your tank. You have the bottom, the middle and the top. Let's start at the bottom, shall we?
Bottom is usually where your cleanup crew is. That's algae eaters, plecos, cories, etc.
A school of at least 6 corydoras julii or sterbai is great:

or you can get a school of oto cats: http://badmanstropicalfish.com/profiles/oto_cat.jpg
Get a school of at least 5 of these (tank minimum: 15 gallons). They eat algae.
I would suggest that you DON'T get a plecostomous. Most of them grow to 18-24" and are poop machines. They will dirty your water very quickly. If you MUST get a pleco, get a bristle-nose, they only get 4-5".
If you get any of these fish, be sure to supplement their diet with zucchini slices, spirulina pellets, and shrimp pellets, as they will not get enough food otherwise.

Next, you want your mid-to-upper range. A school of 8 tetras is great for this level.
Some nice fish are (choose one of the following):
neon tetras http://img225.exs.cx/img225/3290/neontetra6mc.jpg
cardinal tetra http://www.thetropicaltank.co.uk/Fishindx/Fishpics/cardinals.jpg
lemon tetra http://www.aqua-fish.net/imgs/fish/034.jpg

glowlight tetra http://www.solodvds.com/images/fish/Hemigrammus_erythrozonus_s.jpg
zebra danio http://www.winternet.com/~mchristi/fish/zebradanio.jpg
... the list goes on and on and on.

You'll want a centrepiece fish, I suggest either a pair of kribensis cichlids:

Or a pair of bolivian rams:

Or ONE dwarf gourami:

Be sure to keep up with weekly water changes of about 20-40% of the water.

And above all, before you buy anything, go to your local fish store, take a look around and write down the various fish you like. Then come home, research them, ask questions about them, before buying them.
