Stoplight Parrotfish (Sparisoma viride): Ultimate Care Guide

Stoplight Parrotfish, also known as Sparisoma virde, are a gorgeous and colorful species of fish. They aren’t usually held in private tanks; they’re mainly reserved for public aquariums and very skilled aquarists. Stoplight Parrotfish are known to reside in coral reefs, which means you can add them to a coral tank if you choose. Read on further for plenty of information about the Stoplight Parrotfish and why it would make a great addition to your tank if you’re skilled enough.

Stoplight Parrotfish is a coral dwelling species native to the waters in Florida, the Gulf of Mexico, the Caribbean sea, and Bermuda. They’re a very colorful species with a long, almost beak-like mouth. Their name, Stoplight Parrotfish, comes from a large yellow spot that develops near their pectoral fin; it is only visible once they are fully mature. Inside that mouth is a set of teeth with rapidly regrowing enamel, allowing the Stoplight Parrotfish to feed on tough algae and coral. One of the most exciting characteristics of the Stoplight parrotfish is their sex. So If you have more females than males, chances are that some will change their gender to male. Which means they can change their gender based on their own environment and needs.

Stoplight Parrotfish Habitat

Stoplight Parrotfish are native to shallow coral reefs that haven’t been disturbed by people off the coast of Florida, the Caribbean Sea, Bermuda, Brazil, and the Gulf of Mexico. They are found more frequently in reefs in the Caribbean, where they are critical to the ecosystem. Branched finger corals that are around 2 centimeters wide are the perfect habitat for them. They are also more likely to be found in offshore reefs due to the amount of fishing near inshore reefs. Stoplight parrotfish tend to only be active during the day, when they’ll swim around, usually foraging for food. They’ll usually hide in the reefs or under coral boulders at night time.

Stoplight Parrotfish Predators

Stoplight Parrotfish are only aggressive towards their own species, which means they may get taken advantage of and preyed upon by more dominant and aggressive fish. Yellowtail snappers are native to some of the same areas, and they have been known to prey on Stoplight Parrotfish. Stoplight Parrotfish have also been known to be eaten by Bar Jacks, Nothern Red Snappers, Dog Snappers, and Moray Eels. They are also a decently popular eating fish, which means humans are one of the biggest predators to Stoplight Parrotfish. Not much is known about how Stoplight Parrotfish react to predators. Some other parrotfish, such as the Queen Parrotfish, are known to spread their fins and attempt to bite or chase away the predators. Some species of Parrotfish secrete a mucus-like bubble to sleep in, which masks their scent from predators.

Stoplight Parrotfish Care

It is not easy to care for Stoplight Parrotfish, which is why they usually aren’t recommended to inexperienced aquarists. They feed on coral, which means that you need to have plenty of coral in your tank for them to not only feed on but to hide in. They will also sleep on the coral in open areas so that they can quickly escape predators if necessary. The size of the tank required to keep a Stoplight Parrotfish happy and healthy is enough to scare off most aquarists. But if you are skilled enough and research enough, you should be able to adequately house a Stoplight Parrotfish comfortably.

Stoplight Parrotfish Temperature

The native habitat of Stoplight Parrotfish is coral reefs in tropical waters. That means they need to have their tanks kept at or within a specific temperature range in order to keep the Stoplight Parrotfish healthy and happy. The water temperature of Stoplight Parrotfish needs to be between 25.4 – 28 degrees Celcius or an average of 27.2 degrees Celcius. Or 77 – 82 degrees Fahrenheit, an average of around 80 degrees. You’ll likely need a heater in order to reach and maintain those temperatures.

Stoplight Parrotfish Water pH

Water pH levels are extremely important in any tank. Any slight fluctuations could cause irreparable damage to the species in your tank. There is no known perfect pH level for Stoplight Parrotfish, but there are rough estimates that you should follow. You should aim to keep the pH level within the range of 8.1 and 8.4. If you regularly check the pH levels, you can catch any issues before they become a significant problem.

Stoplight Parrotfish Lifespan

The lifespan of any fish, or pet, for that matter, is very dependent on the care you give them. If you neglect them, or don’t feed them a balanced diet, or just miscare for them, then their lifespan will quickly diminish. The average lifespan of Stoplight Parrotfish is between seven to nine years. Some species have been known to live between 15 to 20 years, with the oldest known Stoplight Parrotfish reaching 30 years in age.

Stoplight Parrotfish Size

Stoplight Parrotfish are not a small species; they can grow pretty large, which makes them harder to keep in captivity. A fully grown, male Stoplight Parrotfish can reach upwards of 22 inches in length or nearly 2 feet and almost 4 pounds. Their larger size means that they aren’t easily preyed on by other species. But, anything significantly bigger than the Stoplight Parrotfish will not hesitate to eat it, but that shouldn’t be an issue to these kept in captivity.

Stoplight Parrotfish Tank Size

Stoplight Parrotfish can reach up to 2 feet in length, and they love to sleep on and swim among coral reefs. Due to the larger size of the Stoplight Parrotfish and their reliance on coral reefs, a larger tank size is absolutely required to keep your fish happy. A recommended tank size for Stoplight Parrotfish is a minimum of 200 gallons. That massive size means that most aquarists won’t even have room for them, let alone the skill to take care of them.

Stoplight Parrotfish’s preferred diet is algae that are found on coral. Their mouth is perfectly designed to help scrape those algae off and eat them. They have a beak-like mouth, and their enamel rapidly regrows, allowing them to get as close as possible to use their teeth to scrape the algae off the coral and eat it.

Another vital aspect is temperature; they come from warm, tropical waters. That means their tank needs to emulate those conditions; the easiest and most efficient want to do that is with a heater. Lighting is also essential, now just for the species in your tank but for the growth of the coral in your place in there. You’ll likely want to keep the lights on for around 8 – 12 hours a day, which helps emulate an average day in their natural habitat.
