Congratulations! You will enjoy the school. I had 8 at one time (both white skirt and black skirt) I love them! From the front just after feeding they look like birds! Adorable! I inherited a betta and wanted her to be able to swim, so I re-homed my skirts in the off chance they might have nipped her. Since they were so busy chasing eachother they probably wouldn't have noticed her, but, I didn't want to risk it.
I am so happy I joined Aquarium Advice! I have met some awesome people here!
