I have six rummy nose tetras in my 55 gallon tank. They appear to be aggressively chasing and possibly even nipping at my forktail rainbows. One in particular, seems to be getting harrassed.
Any idea(s) as to why what are normally peaceful fish, seem to be acting agressively towards another peaceful fish?
