I want to eventually add some sort of buddies for my betta, and I figured I would test it early before he gets too territorial. So I took two lingering female guppies from my 20g, put them into the container I bought the betta in, and submerged it into the betta tank. At first he didnt even notice, but eventually he did. He just swam over, did a few laps around the container, flared a little, then calmly swam back over to his side of the tank. They are all still in the tank (guppies still in container just for safety) but no signs of aggresion what so ever. Looks like I might actually be able to put a few tank mates in with this fella. Any Ideas?? I might try my hand at breeding as well??
