I have a crowntail betta in my 29 gallon tank with 4 bleeding hearts, 1 algae eater and 2 zebra nirite snails. With all the other fish in the tank with him, he gets upset with the snails in the tank lol. he'll swim up the them once in a while or if they get too close to him he swims right up to them and flairs his gills at him. I find it kind of funny :laugh:. He flairs at them and they just keep on going or they tuck into their shell and wait for him to leave. Has anyone else had betta flair at snails or is it just my betta? lol
