| Tosh,
The most aggressive fish for the set up you have planned are going to be the two angels and the yellow tang.
Personally, I'd go w/ the two angels instead of the yellow tang, but thats just cause I'm not real fond of yellow tangs....
If you decide to go w/ both angels there are two ways you can go about doing it......get two small angels and place them in the tank simultaneously: This allows them to be in a new environment where neither of them have territory picked out so they will have to adapt to each others presence while dealing with the new surroundings,
Or: Buy one small angel and add it to the set up...wait a few months, and add a larger angel, and rearrange the rockwork (territory) while the new angel is acclimating....
There is still a chance that the two angels wont coexist peacefully w/ each other.....in that case, you can remove one, and safely add the yellow tang...
But I've had good results keeping angels together in smaller tanks than your 90 in the past doing what I mentioned above.....
Good luck,
Nick |
