I started my reef tank a month ago and currently have a blonde naso tang (3-4 inches) a clown tang (5-6 inches) a coral beauty (3 inches) and two juvenile clown. It’s 75 gallons standard size (I know it’s small for the fish but it’s not their forever home). My question is at what size the fish reach should I upgrade the tank size. Going to upgrade to a 200-250 when I do.
