Shockingly Aggressive Dojo Loach

[MrNiceGuy]

i just witnessed one of my two golden dojo loaches viciously chasing and attacking one of my dwarf frogs. it was pretty disturbing actually. at one point he had the frogs foot in his mouth. i thought maybe it was just a crazy one time occurrence but soon after he was chasing the frog and trying take a bite outta em. im not sure how much damage a dojo could actually cause, the frog didnt appear to be physically affected... it still doesnt sit well with me though. is this common at all? i thought they were all very peaceful. maybe it was just a hunger thing, i just fed em to see if that'll change anything
