What would be good fish? And not ones that don't last long or are very tiny. I'm thinkin about kinda big fish...

how about angelfish? I've seen them in larger octogon tanks and they look pretty great.
If looking into more than one species make sure that they are compatible. Not all fish are friendly!
The rule for keepin fish is to keep one inch of fish per gallon of water. This translates to 30 one inch long fish, 15 two inch long fish, 10 three inch long fish... etc...

You can only go so big with a 30 gallon of any shape. Aren't the octagon tanks a little tall? I can't remember. Tall tanks are not the greatest for most big fish. Angelfish are probably the largest I would try. You could also try a few Rainbow fish like Bosemanis, Turquoise, Reds, etc. Those species usually max at 6" and they're simply beautiful. I'm assuming you're thinking freshwater.
Keep in mind though that most fish like side to side swimming. Longer tanks are more effective, but you can still work with what you have. Octagons are cool tanks. Just don't exceed an inch of ADULT fish per gallon. If you can keep under that, you'll have better water quality. Good luck :)

30 Gallon Octagon Fish Tank

Hello, it is really going to depend on what kind of fish you are going to put in there to decide how many. You will also need to know how big the fish are going to get b/c you will need to upgrade the size of your tank. For instance you should only put 1 black moore gold fish in a 30 gallon tank but you could put about 5 fancy guppies some ghost shrimp and a couple other fish. Also if you want a big fish consider buying a bigger tank first . For instance I have one tiger oscar he is now 11 inches long and he is in a 70 gallon tank by himself and thats the smallest tank he can be in.

If you haven't bought it yet, I would recommend not getting a tall tank. They're not very good for oxygen exchange because there's less surface area. Wider is almost always better. The exception would be things like Angelfish, Discus, and Seahorses. They all prefer taller tanks because they tend swim up and down instead of back and forth.
A pair of Angelfish would be cool, if you're willing to do the research and maintain the right water quality for them. I don't consider them a good beginner fish. Discus and Seahorses definitely aren't for beginners.
If you do get a tall tank, maybe try something like Rainbowfish. They're gorgeous, colorful fish that are really easy to care for. Here's what they look like in a 75gal: http://www.csd.net/cgi-bin/cgiwrap/cgadd/showpic.pl/75g_042802_med.jpg
No matter what you get, make sure you "cycle" the tank before adding fish. There are lots of websites that can walk you through the process, but it is a MUST for a new tank.
There really isn't any kind of fish that doesn't "last long". Most fish live 5 years and up if they are properly cared for. Everything comes down to maintaining the water quality.

A 30 gallon would limit you to the types and numbers of marine fish you could get.
What kind of fish and how many depends on the species and the demeanor.
Most cichlid species are aggressive and territorial. You wouldn't be able to keep too many.
The 'community' fish like angels, tetras, danios, guppies, mollies, swordtails, and gouramis you could keep in considerably bigger numbers.
A peaceful tank with larger sized fish, you could probably keep several angels or maybe get away with a single discus.

That is entirely up to you, keep this in mind:
1. 1 gallon of water for 1" of fish (in length) - this avoids crowding in the tank
2. make sure the fish you choose are not territorial, otherwise there will be some fish lost.
Make this your best answer!

It doesn't matter what kind of fish you choose as long as you make sure they can live together in the same environment. If you are going to mix species you have to make sure the fish are not aggressive, or one species will dominate and stress out the rest of them. You can choose tropical, cold or fresh water, or salt water. Salt water and tropicals obviously need to have heaters for warmer water temps.
Most pet shops list which fish will live better together, and also show their level of aggression.
Salt water tanks are harder to maintain, and must be checked for certain chemical balances before fish can even be introduced. My 35 gal. octagon fish tank is a salt water tank. Right now I have two blue damsels and some hermit crabs, because they are hardy and can withstand changing temps, etc.
Check it out with the place where you are going to buy your fish. They can help!

You could put maybe 5 fish in there. Angel fish and clown fish are good fish choices. But you need a heater, saltwater,and an airator
Hop this helps!! :-)

If you were planning on going for freshwater, I say angelfish, because they can get pretty big, and they're really pretty.
If your going for saltwater, go for something like a pufferfish or something.
Just make sure that, whatever fish you put in there, they all get along with each other!
