Finally Making Some Decisions

[greenmonkey51]

After not doing much to my 75g for months, I've finally decided on some fish I want. I have a couple of true percs and a finespot wrasse. The clowns may not stay, but I want to try and add a pearl scale butterfly, eibli angel, and kole tang. Those 3 are pretty set. I would really like to try a burgess butterfly if possible. What are the rules concerning multiple butterflies. I really like them and would like to have a few.
