We all make impulse buys. I did it and had to catch damsels out of my tank. Then I did it again and had to catch a blue sided fairy wrasse out of my tank and take it back to the LFSOh, crap. I forgot to "research" when I bought this lion.
In all honesty, I know (and knew) the risk. I still feel horribly about my blue fish. I am a bad fish parent.
