Do not buy this fish unless you wanna see action ... Like FISH GONE WILD kind of action! This fish has a Mike Tyson/Muhammad Ali complex and will kill anyone in his way. They become especially rabbid after a hearty meal, I guess they're mad at the other fish for eating too! They killed two of my fish, I learned the hard way, dont make the same mistake.

Oh dear, just bought a 4 stripe damsel. Pet shop said it would be ok with other fish. I have not seen any aggresion as yet, but will keep a close eye on it and see how things develop. All comments on this fish are conflicting.

I bought a Four striped damsel, Blue devil Damsel, and yellow tail blue damsel all together... The four Stripe and blue devil swim around the cage like best buddies while the yellow tail has hid in the corner under my live rock since I have had him, Last night was the first time I seen him come out into the open, and that was with the lights off. There has been no aggression at anytime from any of the 3 since I have had them.
