Just upgraded to a 60gal. Would it be possible to add a flame angel to the tank with an existing bicolor? Moved all liverock etc. into new tank so territories have not been established yet.
That's a pretty risky maneuver, but I think it really depends on the individual fish. I tried adding a bi-color to my 150, my flame immediately declared war. I've seen it work, just keep a close eye on them if you try.
You can mix angels. people do it all the time. Its hit or miss and a longer tank is needed. Two large angels would probably work best if started aout as juvis and in a 150 gallon tank. Lots of live rock for hiding places is best as well.
Bi colors get bigger and are mean as adults. Since he is already established I wouldnt try it. I have one. They are gorgeous fish
Post pictures of your tank please.
