sorry to hear that Sunstrip....
lol.. i know its not funny, but yes, the true paradise fish is a meany for sure. They are aggressive and territorial usually with their own species, but I see that you are not having that kind of luck. There are other species of paradise fish that are much more nicer.. seems you dont have one of those.

I have no advice for you.. as I dont know what you can do with the guy now that you have him, other than trying to see if a
LFS will take it off your hands!
I feel your pain!
