Yeah my wife picked out that one. I bought a 6 line to surprise her because she loves rainbows, then I took her to the fish store with me a few weeks later and she fell in love with that fish. The owner said it would be fine and there would be no conspecific issues. The six line terrorized the crap out of the lubbock for a few days. One day I was feeding and the lubbock was all happy swimming around with all the other fish but the six line was no where to be found. Later I found the crispy six line carcass in my cat's hideout. I guess he got chased right out of the tank and then my cat found it. Moral of the story is when a LFS owner is hurting for a sale, she may blow a little smoke up your ass so you'll drop 30 bucks.
It's all good though. I am happy with the fish I have now. She names all the fish and I believe that one she call Marley as in Bob because he looks all tie dye.
