I also thought glass cats got bigger, but after doing some research, there are 2 different kinds. Asian glass cats (Kryptopterus minor), seen here only get around 3 inches, while African glass cats (Parailia pellucida), seen here get 6 inches. The African glass cats have an opaque black spinal chord, while the others have a clear spinal chord.
If you have the smaller ones, you should still upgrade the tank for them and the angels. They need a group of atleast 6, more if you can. All the angels and the glass catfish still won't be happy in a 30g IMO. I'd go bigger.
Check in the local newspaper and on Craigslist.com for used tanks. Used tanks are fine to use, you just need to leak test them for a week or so to make sure. If the seals leak, all you need to do is resilicon them. I have found some killer deals in my local paper...75g tank and stand, $60....too bad I don't have room for it. I will definitely never buy a new tank again....unless its a small one and affordable (under $30). You can use some pool filter sand as substrate if you can't find cheap gravel....and other equipment isn't all that expensive.
