I was on a family trip last year to another hawaiian island and I was told that there was a tank in the car rental area. There was a 55 gallon saltwater tank with dead coral, a yellow tang, a zebra eel, a Hawaiian flag fish, a soldier fish, a damsel, and a dog face puffer. Terrible
Rule number one: Always research a fish before you buy it.
Rule number two: Always cycle your tank.
