The Kole Tang is commonly referred as kole yellow eye tang, yellow eye tang, or yellow eye surgeonfish. It has an oval shaped body with bold markings that change with maturity. At the juvenile stage, it basically shows a yellow-gold to tan color combined with stripes and spots. The color gets darkened and changes from blue to burgundy as it grows. It is best to keep the Kole Tang in a tank not less than 40 gallons, along with plenty of swimming space. Since the Kole Tang is aggressive towards other tangs, we advise you to keep only one per tank. The Kole Tang is considered reef safe and will not harm sessile invertebrates in the reef tank. It eats meaty foods along with other fish in the aquarium, and it also benefits from the addition of plenty of marine-based seaweed and algae. Like all other surgeonfish, the Kole Tang also features a scalpel which is a sharp spine at the base of its tailfin, which is used for protection and helps in establishing dominance. It is well-known for its algae eating habits, and therefore we recommend you to provide them with some live rocks that encourage the growth of natural algae, and also some algae pellet if the algae growth is insufficient. It is best to keep many hiding places and spots for them to rest during night. The Kole Tang thrives well in a temperature of 72-78 degrees Fahrenheit, and pH of 8.1-8.4. We also advise you to take pre-cautions before handling this fish, as it has a scalpel fin that can inflict painful wounds. It is a relatively peaceful fish and housing it with other aggressive fish is a big No, as it can be ingested or harmed to death by those aggressive fishes. Since the Kole Tang doesn?t produce mucous as natural defensive mechanism, it is susceptible to marine ich so proper acclimation and care is required.
