The other day I saw a potters angel and I had to pick it up, I was told that the Potters would usually be the aggressor and since my Lemon Peel angel is bigger it should be ok. When I put the Potters in the Lemon Peel would just go after it no matter what and even look for it to chase it around so I put the Potters in the sump. I am thinking of selling one of them and keeping the other. Any advice?
