About a week ago I finished off my tank with its last addition, a Rusty Dwarf angel. My new friend is spendy all of his time hidding in a hole in my live rock, hugging the rock, I haven't even been able to cox him out to eat. I was wondering if this was a typical behavior for dwarf angels or is it worse for my little friend. Water parameters are perfect, tankmates are 2 Ocellaris Clownfish, 3 green chromis, 1 Fridmani Pseudochromis, 1 scooter blenny, 1 purple firefish...
