Here you go... now start plumbing
Going from FW to SW. It is funny to me what SW keepers consider aggressive. Hear it time and time again, one tang per tank. Yeah maybe if you have a small tank, but even then Tangs probably aren't a great option as the majority get fairly 'large' and they really like a lot of space to graze. I have 5 now, and when i add a new one, the Powder Blue goes after it for 3-4 hours. Then the next day its like the new fish has been there since the start with 0 aggression. They actually even seem to 'enjoy' each others company. Look at the pics the 5 tangs are all within a foot of each other in both pics. This wasn't a coincidence either. They seem to actively graze as a group moving about the tank - even though they are all separate species. With two in the genus Acanthurus and two Zebrasoma and a lonely Naso for now.
