Has anyone ever kept these two together? Im talking about sabre tooth tetras, not sure if it is paraya or payara. I just know that my pikes dont seem to care for other long bodied fish. Took forever for my big sveni to accept my silver aro, now they follow each other around, but the pike still bashes it once in a while. I was curious cause I ran across some 6'' beauties for $20. Cool looking fish.
