I don't suggest putting anything else in the tank, but if you feel that you must, shrimp are the way to go, as they will not produce a whole lot of waste that will harm your fish.
Sorry Loppy, but shrimp are very sensitive to water conditions, I doubt they would survive the 100% water changes, the pH swings, the ammonia spikes Etc.
I wouldn't. Really. 1.5 is barely enough room for a betta. Just keep and betta in it and everyone will stay happy. Shrimp would be the only thing I'd add. Bettas really don't LIKE company anyways.
also don't add cory catfish!
You would need at least 10 gals. And they need a lot of them to be happy, as they are shoaling fish. Also salt burns then :(
Personally, if you feel the need for more living things in a tank that size, I would suggest a live plant. No.. they don't swim around and greet you when you enter the room, but it can be very rewarding to take care of them, and they do great things for your tank by neutralizing ammonia created by your betta. Your betta would love you for it. Just my .02.
Loppy no offence, but your being ridiculous. Listen to these guys, especially dramaqueen, they know alot more than you do because they have had ALOT more experience and MANY more fish than you.
Throwing in my .02 as well, you might want to know that it could end up very bad for either one or the other. Your betta might end up simply killing and eating the shrimp, or shrimp have been known to latch onto betta tails. In a smaller tank, I think the risk of death or injury to one or both creatures increases dramatically. I say keep your betta alone, and save up that money to upgrade his tank size, until you have a large enough tank to actually get him a couple of "buddies" and not have to worry so much.
