Frogspawn Coral is a large polyp stony coral. They are native to Southeast Asia, Fiji, Australia, and several other places worldwide. Frogspawn Coral can be found in a wide variety of colors. The most common colors of Frogspawn Coral are green and yellow. The tentacles of Frogspawn Coral are usually different colors than the polyps. The tentacles can be white or sometimes even different shades of pink. Some of the more rare Frogspawn colors are orange and blue. Most aquarists don’t like blue Frogspawn Coral because it doesn’t look as exotic as the other colors. Orange, on the other hand, is usually tough to find.

In some cases, Frogspawn Coral is sometimes known as grape coral, honey coral, wall coral, or octopus coral. One of the most interesting facts of Frogspawn Coral is that their polyps stay out all the time, which makes them even more gorgeous to look at. Frogspawn Coral can withstand a wide variety of tank conditions. Despite that hardy nature, Frogspawn Coral should not be neglected; if it is ignored, it will likely die.

How to take care of Frogspawn Coral

Caring for Frogspawn Coral requires a bit of research, but if you carefully plan, you shouldn’t have any trouble adding this gorgeous large polyp stony coral to your tank. Starting with the water, Frogspawn Coral has some specific requirements. The water temperature of a tank containing a Frogspawn Coral should be between 78 degrees Fahrenheit and 82 degrees Fahrenheit. The required pH level of the Frogspawn Coral is around 8.2. Next, you need to make sure you position your Frogspawn Coral perfectly. They need a moderate water flow. If the water flow is too intense, the polyps will either retract or get damaged. If the water flow in your tank isn’t strong enough, the Frogspawn Coral will not get enough oxygen. A lack of oxygen can lead to stunted growth or even the death of your Frogspawn Coral. Lighting is also an essential parameter for Frogspawn Coral. If the Frogspawn Coral gets too much light, it will likely bleach, which isn’t healthy for the coral. On the other hand, too little light is also dangerous for the Frogspawn Coral; they will starve if they don’t get enough light. You also need to be sure that you don’t place your Frogspawn Coral too close to any other coral in your tank; they won’t get along very well, and one, if not both, will suffer.

Frogspawn Coral Water Parameters

Water Parameters are one of the most important criteria for establishing a tank setup for Frogspawn Coral. Frogspawn Coral requires the water temperature to be within the range of 78 degrees Fahrenheit to 82 degrees Fahrenheit. That high-temperature level means that you will need a heater to maintain it, as any fluctuations in temperature level would not be healthy for any of the species in your tank. pH level is also a critical factor. Any slight changes in the pH level will negatively impact your Frogspawn Coral, which it will do it quickly. That is why it is imperative that you regularly the pH level and ensure it remains at the required level. The required pH level for a tank that contains a Frogspawn Coral is 8.2.

Frogspawn Coral Water Flow

Water flow is vital in any aquarium setting, but it is even more critical when you’re housing large polyp stony coral such as Frogspawn Coral. You need to place your Frogspawn Coral in a location where it will get moderate water flow. If the water flow is too strong, then the polyps on your Frogspawn coral will likely get damaged if they don’t retract. If the site you choose to place your Frogspawn Coral doesn’t have enough water flow, that is even worse. If the water flow isn’t strong enough, your Frogspawn Coral won’t get enough oxygen from the water. In Frogspawn Coral, a lack of oxygen can lead to weak growth and sometimes death.

Frogspawn Coral Placement

Placement in a tank is a crucial decision that one has to make when adding a large polyp stony coral to their tank, which is especially true of the Frogspawn Coral. You also need to consider how your tank is set up when considering placement. For example, the types of lights and water filters you have significantly impact the location where you should place your Frogspawn Coral. If you don’t have strong lights, you need to place your Frogspawn Coral in the middle of your tank to ensure it receives enough light. But, if you have strong lights in your tank, you’re going to need to place your Frogspawn Coral near the bottom of your tank and to the side to avoid them getting too much too light. You need to make sure that you select a location close enough to your pumps to provide adequate water flow but not close enough that they give too much water flow. Finally, it would be best if you didn’t place your Frogspawn Coral too close to other coral in your tank, be sure to give them each adequate space. It may seem like there are many restrictions for the placement of your Frogspawn Coral, but if you follow these guidelines closely, you shouldn’t have any issues.

Frogspawn Coral Temperature

Temperate is an essential parameter of any aquarium. You need to set the temperature to emulate the native environments of the species housed in your tank. Frogspawn Coral is native to Southeast Asia, Fiji, and Australia. One connecting thread between those locales is that they are all tropical environments. That means that the native habitat of Frogspawn Coral is warm salt water. Most aquarists recommend a temperature level between 78 and 82 degrees Fahrenheit. You will need a heater in order to achieve and maintain those warm temperatures. Ensure that you purchase a heater strong enough to cater to your entire tank, as any temperature changes will affect all of the species in your tank.

Frogspawn Coral Lighting Requirements

Lighting is essential for Frogspawn Coral because they get some of the nutrients they need for survival from light. Some may believe that corals are a type of plant and get their nutrition through photosynthesis, but that isn’t true. Frogspawn Coral are traditionally found in indirect sunlight in the wild. They are living animals, although they do contain organisms called zooxanthellae. Zooxanthellae can turn light into sugars and provide a bit of nutrition to your coral; that is why light is so essential for them. You need to be sure that you aren’t giving your Frogspawn Coral too much light; this will be evident if they begin to bleach. Moderate light is the best choice for Frogspawn Coral; you can usually achieve this by keeping them at the bottom of your tank, off to the side. Your best bet is to try emulating the lighting of wherever you purchased your Frogspawn Coral from. Keep in mind that sudden changes in lighting can be very detrimental to the Frogspawn Coral, likely damaging it.

Feeding Frogspawn Coral

Contrary to what some may people may believe, corals are not plants. That means they do not gain their nutrients through photosynthesis. Although, Frogspawn Coral does contain an organism known as Zooxanthellae, which can turn sunlight into nutrients. Unfortunately, the nutrients provided by the Zooxanthellae are not enough for the Frogspawn Coral to survive. That means you need to supplement their diets with more food. You can feed your Frogspawn Coral frozen foods that are high in proteins; they also tend to end plankton and brine shrimp. Some aquarists have even had luck feeding their Frogspawn Coral pellets, although, for most, it may be trial and error to see if your coral will like the pellets.

Frogspawn Coral Size

The fully grown size of any coral is an important thing to consider when planning your tank. You need to give them enough room to grow without hitting obstacles such as the tank walls or other coral. On average, a fully grown Frogspawn Coral tends to measure just under 10 inches, usually around 25.4 centimeters. You need to make sure you give your Frogspawn Coral at least 6 inches of space around it on all sides when you place it.

Frogspawn Coral Growth Rate

Most experts have said that Frogspawn Coral’s growth rate depends on the type you have. An additional factor that affects their growth rate is their care. Frogspawn Coral won’t grow very quickly if you give them poor maintenance or neglect them. If you do care for them adequately, most varieties of Frogspawn Coral can reach their max size of just under 10 inches in around six months. So that means if you want your coral to grow quickly, you have to care for them properly.

Fragging Frogspawn Coral

Fragging Frogspawn Coral can be dangerous to the coral, depending on the type of Frogspawn Coral you have. It is easier and more likely to be successful if you try to frag branching Frogspawn Coral instead of the wall variety. The first step is to select a healthy piece of Frogspawn Coral; you need to be sure that both the color and polyps look good and there is no visible damage. Remove your Frogspawn Coral from the water, and prepare to cut. You want to make a quick cut, usually using a bone or electric saw. After you make the cut, place the Frogspawn Coral in iodine and in a stress-free environment until it recovers. As for the piece you cut off, you’ll want to glue it to a rock and place it in an appropriate area in your tank for growth.

Frogspawn Coral Not Opening

The polyps of a Frogspawn Coral not opening clearly show that something isn’t right. That issue could be a fish, such as angelfish, nipping at the polyps. It could be evidence that there is something wrong with the water parameters or the water flow it is receiving. Some aquarists say that just performing a water change could be enough to get the polyps to open back. But as soon as you address the issues, the polyps on your Frogspawn Coral should open back up.

Frogspawn Coral and Clownfish

Housing Clownfish and Frogspawn Corals should be avoided. Some Clownfish may mistake the Frogspawn Coral for a Sea Anenome and may try to swim in it. The Frogspawn Coral will not like the contact from the clownfish and will likely close its polyps. If the polyps of a Frogspawn Coral are closed, then it can’t eat.

Where can I find Frogspawn Coral for sale?

Frogspawn Coral is one of the most popular varieties of coral, which means it shouldn’t be hard to find locally. Most aquarium stores will likely carry them in stock. Frogspawn Coral can also be purchased online; just be sure to buy from a reputable seller. Frogspawn Coral can be a bit expensive depending on the size and color. Most varieties of Frogspawn Coral begin around $100. However, they sell for up to $500.
