Can I add any of these fish to my tank?

I have a 180 fish tank 60 lbs of live rock and 60 lbs of base rock and i have 1 bicolor angelfish can i add another angel fish, i want to add a coral beauty? and how many tang fish can i have in the same tank?

• Answer:

  Angel fish normally will fight with each other so i would skip it due to the fact that they are expensive fish. As far as tangs go the will fight brutally in the tank when there is more then one. However with a 180 you maybe able to get away with two but its a 50/50 chance. But keep in mind the tang that was in their first will beat the new tang as soon as he sees it. This can lead to stress, not eating and eventual death. You can try re arranging the live rock right before you put the new tang in the tank. This has worked for me to break up aggression and territorial battles between tangs.
