Two days ago I decided to go buy a new plant for my betta boy. He absolutely loves it and there already is a huge bubble nest around it. Yesterday, I noticed that he was swimming rapidly and sort of flaring around one spot, as if observing something in a rather predator manner? Maybe I'm wrong...

hi guys. I have a yellow mystery snail who is usually very Active but lately has not been. I haven't changed anything with the tank except a slight increase in water temperature for a sick betta who is getting over sbd. Should I be worried about my snail or is this normal?
