Thanks.
I knew there was a chance for aggression between the angels, but figured it to be more of a problem between the 'Dwarf' species.
I would be much more worried about 2 Coral Beauties or a Coral Beauty and a Flame Angel being kept together (for example). Though I have seen the two kept together in much smaller tanks without incident.
Yet, the risk is still there and I would never openly give someone the advice to do the same.
IME, encounters between angels usually involves quite a bit of 'aggressive showing/flashing' and some chasing, but nothing serious.
I've seen much worse between Tangs, Clowns and Damsels yet so many folks keep multiples of these fish, as well.
My Cichlid tank is much more of a gladiator battle coliseum, any day.
Fact is, I knew the risk, rationalized it (75G, large tank, lots of hiding spots, one dwarf species, one not), and took the gamble. If things do get ugly, believe me when I say the Coral Beauty will be the 1st to go. The Poma stays.
On a different note, it appears that alot of the new macros took the shipping pretty hard and are now turning white/bleaching. Which means they probably are going sexual. I'll keep a close eye on the tank and the water the next few days. Some water changes may be required.
