Group of 3-5 too large for a 5.5g with a betta? I saw them at the LFS, and holy crap are they tiny and uber cute. And I wantz themz... lol. I kinda already know the answer to this, but It would be a 5.5g NPT with Ankou as basically the only other inhabitant.
Jodah,
Yes, in my opinion too small,sorry. You would need at least a 10gallon because the catfish are active! I have a 10 gallon with 4 Julli Catfish,same size as the Pygmy and wow, they are all over! The bio load will get to be too much as well. And, you need places for them to hide from each other (which I'm sure you knew already). Not sure how to make that work in a 5 gallon, I only had critter keepers, 1.5 or my now 10's. There are others here that know better then me! This is my first time mixing them! They are so cute though! :) Good luck!
I've kept them before and they are great active bottom-feeders. I'm going to agree with animallover and say that you would need at least 10 gallons of space for what you're thinking of. If you ever do decide to upgrade, though, cory cats and bettas seem to co-exist pretty well.

Julii are much bigger than pygmies....
Nevertheless, I'm with the other guys on this. Even though pygmies are crazy small, they do need a much bigger footprint than a 5.5 can offer. I'd wait til you can have a ten. Then you can have a full school of 6-8, which will make them much happier. :)
I have a 10g, and a 20H. Just no money to buy equipment for them (just lost my job recently >_<) so, for now, everything is on hold till I get a job. lol.
