I got my betta and snail about 3 months ago. Originally they were in a 1 gallon acrylic tank for a couple weeks until I became educated on the needs of betta fish. Currently I have a 5.5 gallon tank with a filter and heater. Over the past 3 months there have been no problems with the betta and snail being together, but lately the betta has been flaring at the snail. The snail closed up and was just floating around the tank for a day not sticking to the walls or anything so I took him out and he seemed fine, so after a water change I put him back in and the betta is still flaring at him once in a while. There is no nipping or anything like that, so I just don't want them to be stressed out for no reason. Anything I can do, or would separating them be the only option?
