Would this be a better alternative? Thank you for all help in advance.
I think the confusion comes from the differentiating of the different angel families. In truth, there are 4 general catagories: The larger Pomacanthus/Holocanthus, etc, The med/large Genicanthus/including some Holocanthus, the medium sized Dwarf Angels and lastly the Pigmy Angels. While dwarf and pigmy Angels carried the family name centropyge, it's only the pigmy branch of these that will do okay in a smaller tank. The dwarf Angel branch should really be kept in larger ( than a 20 gal
.) tank, like a 4' long or larger.
In your case, the Potter's is a dwarf angel and would be better in a larger tank but the Fishers is a pigmy so it would be okay in your tank and a better choice (IMO
) than the Potters. There are also other pigmy Angels that you can consider such as the Atlantic Pigmy, Pacific Whitetail, African Flameback, Atlantic Flameback and Atlantic Replendent (if you can find them and afford it
) to name a few.
As for what you have read on other sites, the info may have come from someone who clumped all the Centropyges together forgetting that there are 2 branches to that tree
That might acount for the 20 gal
I hope this helps clear things up a bit for you
