i have a fluval 205 on my aquarium and it is always on but my bristlenose keeps ramming it and sticking his head in it i thought he got caught originaly but when i swithced it off he swam away. then when i turn it on he goes and sticks his head in it? and he does the this multiple times and what i dont understand is that its the filter outlet hes sticking his head in. you know the one that blows out the water making a current ?
