What would be the best tang for a 57 gallon fish tank?
I recommend the Yellow Tang. The yellow tang is a very commonly kept as a saltwater aquarium fish. They can grow up to 8″. They require an aquarium of at least 80 gallons, while 150+ gallons is even better. They are usually very hardy, although, like all Tangs, are quite susceptible to Ich and other common saltwater diseases. They are semi-aggressive fish. They normally get along fine with other semi-aggressive fish close to their own size. Can be kept very well with other yellow tangs in pairs or in a group in large Tanks (150+ gallons). Possible other tankmates include fish like cardinalfish, large clownfish, lionfish, eels, or other different-looking Tangs like the blue tang or Achilles tang. They are reef-safe, and can be kept with any invertebrates in a reef aquarium.
