Thanks for the help guys - glad to hear it should work out as long as my bettas aren't too frisky. They are relatively enthusiastic flarers when they can see each other so I'll have to keep an eye on them. I was thinking about taking them out for the next water change and then putting them in the opposite side of the tank at the same time as I put the shrimp in (one on each side). That way they'll be establishing new territory at the same time. Hmm.
And of course I can definitely always move the shrimp to the community tank which is understocked at the moment. I don't think bioload will be an issue in my 10G, because I have a strong (baffled) filter on it and I do weekly water changes, but I'll make sure I'm testing every day when they're added.
I've actually heard the opposite, that they have a small bio load for their size, so I'll definitely have to do some more research. I've read through their info on a ton of sites and it's just not complete info. Maybe Bing will have the answer. And I'll be feeding algae flakes and bloodworms (maybe with some zucchini every now and again). Right now my betta are eating bloodworms and high quality pellet food. My lid is tight but there is a very large opening for the heater that I'll have to cover - thanks for reminding me that they're good at escaping! Wish me luck! Any additional advice and info is greatly appreciated.
