Funnily enough, this isn't the first time this frog has 'discovered' the bar. On the first day the filter was installed, the same thing happened until the spray bar was adjusted. I wouldn't mind this as much if I didn't have the tank in my bedroom. Needless to say, hearing *plop plop ... SPLASH* isn't very conducive to sleep, it also seems to be stressing the other frogs. I'm trying to think what would be a good way to encourage the frog not to do it.
