Earl, wish I could help. Just got the Purple and he is turning out to be a little bully. If he was showing signs of being layed back and not a bully I would love to try them out together. It would still be a stretch but we could monitor the situation and be ready to pull the little fellow if the Purple got out of hand. For anyone reading in the surrounding area this is a sweet little tang very healthy and entergetic. Earl, I 'm out of town this week end I'll talk to you on Monday.
PS The copperband(Tootsie Roll) is eating and looking good and the
Purple Tang(Barney) is starting to show signs of the LLE going away(long process though, he has it pretty bad).
For those that are wondering the rule in my house is I pick out the fish , but my wife gets to name them!!!
Talk to you later, best of luck
Kevin
