5 most beautiful large-type hard corals

The photos in this article are likely to pique your interest in adding large-growing stony corals to your aquarium. And it’s no surprise because they’re even more beautiful in person than they are in photos! However, the majority of these invertebrates are fickle and difficult to care for. Furthermore, almost all of them are most at ease in large basins of a hundred, if not two hundred liters. On the other hand, these are all challenges that seasoned aquarists are unfamiliar with. As a result, it’s still worth a shot!

Tubastraea

Tubastraea

Tubastrea (Solar coral) is practically the only large stony coral you can afford if you have a small aquarium. The colony’s diameter rarely exceeds 13 cm, allowing it to thrive in basins as small as 40 liters.

Weak lighting and high current are best for tubastrea. The colony will become overgrown with algae if this does not happen. Because the coral is quite voracious, you should place it in the aquarium so that you can feed it at least twice a week. Crushed fish and meat plankton are its main sources of nutrition. The tubastrea polyps will become “well-fed” and grow in size if you do not cut back on the feed. They are usually drawn inside to the colony during the day, but once they have become accustomed to feeding during the day, they remain open.

The coral reproduces asexually, producing bright yellow polyps in various parts of the aquarium.

Trachyphyllia

Trachyphyllia

Trachyphyllia is a spectacular single coral with a bizarre shape that resembles the human brain. They stand out for their unique color transitions from green to metallic and cream to pink, as well as their ability to fluoresce when exposed to actinic lighting. Aquariums with a volume of 190 liters or more are recommended. It should be noted, however, that these corals are toxic to small fish. Centropyge and surgical fish, on the other hand, can pluck and kill them.

Trachyphyllia forms colonies up to 46 cm in diameter. They prefer dim light, but if they gradually become accustomed to it, they can feel at ease in bright light. They are stuck to the ground when they are young, but they are eventually released.

They have a symbiotic relationship with zooxanthellae, which provides them with nutrients. They do, however, require additional feeding.

Physogyra Lichtensteini – Bubble coral

Physogyra Lichtensteini

Another coral that will look great in a house reef pool with at least 200 liters of water. These invertebrates resemble bubble caps with a diameter of around 30 cm.

Pearl corals thrive in dim lighting and slow currents. Hermit crabs do not get along with them. The blisters are extremely fragile and susceptible to infection. She has long, flailing tentacles and an aggressive demeanor.

The coral’s “head” is made up of small vesicles with a diameter of 3-5 mm that serve as zooxanthellae containers. When they swell, they provide a lot of light to the symbiotic algae that live inside. The bubbles are emptied at night, but the tentacles, on the other hand, stretch out.

Bubble corals require additional food despite their mutually beneficial coexistence with zooxanthellae.

Goniopora

How to Keep Goniopora the Easy Way

Goniopora is a type of goniopora (branched tentacle medulla) that is most commonly found in shallow reefs in the natural world, as it prefers bright lighting. Polyps on long legs form colonies up to 60 cm in diameter, each with a corolla and tentacles around the mouth opening. Goniopora attracts a wide range of colors, including brown, greenish, yellow, and blue. The polyps are drawn into the colony when they are inactive. The coral grows significantly in size in the erect form, so it’s important to give it plenty of room in the aquarium.

Aquarists are inspired by the beauty of goniopora to try their hand at breeding them in captivity. However, only a small percentage of attempts are successful. The coral is a fickle creature. Because the polyps’ legs refuse to grow in the aquarium, they eventually stop rising gracefully above the colony’s base. As a result, the invertebrate animal is deprived of food and dies quickly. Only a system with a constant influx of fresh seawater can increase the life expectancy of these demanding animals.

Euphyllia

Euphyllia coral care and tips

Euphyllia thrives in aquariums and can reach impressive sizes when kept in captivity. It prefers deep water and wave-protected locations. It is made up of large polyps with well-formed tentacles that are slightly swollen and lighter in color at the tips. Fluorescent blue, green, and yellow are the most common colors.

The nutrition of corals is primarily provided by symbiotic algae (zooxanthellae). However, in aquarium conditions, feeding zooplankton and finely crushed seafood is not harmful.

Euphyllia corals are aggressive. Their stinging tentacles can reach a distance of more than 10 cm and inject a powerful poison into their prey. Medium-bright or bright lighting, moderate current, and a water temperature of 24-27 degrees are recommended for keeping in the aquarium.
