The Pygmy Angelfishes by James Fatherree - Reefkeeping.com
"They tend to be quite territorial and, in most cases, two or more pygmy angels will not get along at all. This is especially true if more than one individual of the same species are kept together, which is often impossible in most tanks. They usually wind up endlessly harassing each other."
"Still, in large tanks (100+ gallons) with plenty of structures and hiding places, there’s a much greater chance of successfully keeping more than one pygmy angel. Individuals need to be able to avoid each other when they want to, so giving them plenty of room and shelter is the key. However, I do have to say that even in tanks this size, I’ve had some that just wouldn’t get along no matter what. Sometimes individuals can be particularly aggressive no matter how much space (i.e., territory) is provided.
I’ll also add that if you do plan to try to keep more than one in a tank, it’s best to add all of them at the same time. As is the case with many other fishes, if only one is added first, it may decide that the whole tank is its domain, and be less likely to tolerate the addition of any other pygmies added later."
