So I have the opportunity to get a 3" Burgess Butterfly (Chaetodon burgessi) which is one of my favorite deepwater Butterflies. The tank I have is a 30 Gallon Non-Photosynthetic Reef (30 L x 18 H x 12 W), I'm not sure how fast Burgessi grow since they're a Deepwater Butterfly but what would be the likelihood of it doing well in a tank that size? Realistically, I'll only have it for about a year before I go to Uni, at that point I can see if I can bring it to the Aquarium with me to put in our own Non-Photosynthetic display.
