Chocolate Starfish - 2009-01-01 My Keyhole Angel eats anything, is always busy zubbing around the tank, and certainly not shy. Click For Replies (1) stu - 2010-05-05 I just added a keyhole to my aquarium. It only seems to eat the algae, and the packaged seaweed. No brine shrimp, or flakes. In the picture on this site, it shows a little pale in the face. Mine shows that now too. Is this common? Is it a phase? I did not notice when I first added but it was usually hiding. It has begun burrowing in the crushed coral under the live rock. This is a pretty fish, and I want to catch any health concerns. Reply
