I recently lost one of my fish in a divided tank setup, and want to get a new one. However, I'm afraid introducing a new betta from a pet shop could introduce disease to the tank, and to the healthy fish on the other side of the divider.

Do any of you guys take any precautionary measures before introducing a fish to an existing community?

You could set up a Quarantine Tank. It's a way to ensure no disease in an existing tanks. You could use a Kritter Keeper, or even a Sturdy Plastic Bin.
You just have to keep the fish in there for a few weeks. And then, if it seems healthy, you could carefully put it in the Community tank.

I would use a quarentine tank. A small plastic bin should suffice, precautions should be taken to keep the tank extremely clean and to maintain perfect water quality, you should also check the fish daily for any signs of disease, lethargy, not eating, loss of color, discoloration, white spots, ragged fins, or anything other abnormal.

I personally slowly acclimate the fish are float it in a large bag to monitor aggression. I also add more cover for the the fish to retreat to. The bag method works better as it almost represents the habitat and tank mates the fish will be with

Nitrofuracin. I recently lost quite a few fish so I'm treating everyone with this stuff and using it as a preventative. This stuff kills everything your betta may have.
