Welcome to AA.
In the beginning none of use knew anything about fish. Some of use were smarter than others and asked questions first (NOT ME OF COURSE) then got their tanks and fish. But many of us did it just like you. The "I've done this, now what" method.
Good luck with separating all those fish that don't belong together. I wish I could be more help but I don't know much about the fish you have.
Hang in there though, everyone here on AA will be a great help.
