I have five now. I just love them. I love to watch how their fins flow in the water. All five will come up to take the food from me.
I use a turkey baster to suck up & clean the bottom of the bowls. This also does a 20% water change at the same time. I keep a big pitcher of declor water by their bowls to put back in. This way the water is the same temp. Very easy to keep them clean.
I also change the position of their bowls around weekly. That way they don't get lonely and no one gets hurt.
If you have Betta's please post their pic here.
I would love to see them.
