Love this Passer Angelfish! He is so beautiful and such an interesting personality! He doesn't bother anyone and has actually become friends with our yellow wrasse! They swim attached at the hip looking for food! He is a very mellow swimmer who loves swimming through the rock work to find new caves. He is a little hard to feed when competing with quicker eaters, I let a couple pellets sink in front of him and sink a few spirulina flakes)! I highly recommend him, he is sweet, beautiful, and easy!
