Hej har denne vidunder så jeg lige vil dele den måler 30x24 måske mere.....

IMPONERENDE!!!

Flot

Hej Nybegynder.

Det er mange år siden jeg har set så flot et eksemplar.
Havde selv en der lignede tilbage i starten af ´90 erne.
Det var stort set den eneste koral som rigtigt kørte for mig dengang.
Jeg har ikke rigtig set dem i den størrelse siden. Sikke en "plade" den har. Flot flot.

Erik

takker syntes selv den er nem at passe den skal jo bare ha en masse lys og nogle ok værdier...Ved du evt. om den kan dele sig eller ???

Hej Nybegynder.

Jeg tror ikke den deler sig. Jeg har dog hørt at den, hvis den får en skade, skulle kunne vokse videre og så at sige lukke hullet, så der derved bliver to koraller ud af en.
Men jeg tror ikke det er den "normale" måde at formere den på.
De gange jeg selv har haft en som er skadet, er den altid gået til.

Men jeg faldt over en interessant tråd, som bla omhandler Catalaphyllias formering og hvilke forhold den lever under i naturen.
Det er en længere tråd, men dog til at komme igennem.
Det er på engelsk, men det håber jeg går an.
Det relevante omkring din koral står her:

I've been studying elegance corals for the past 25 years, so I believe I know where they're from. Due to their life cycle, they are actually the best example (I know of) to demonstrate that stony corals prosper in clean, nutrient poor water. Not turbid, murky, or muddy habitats.

Elegance coral larvae can not settle in sandy grass flats or muddy sediments. The first tide change, or storm that moved through would disturb the bottom, and cover the tiny larvae causing it to die. They need a solid and fixed structure to settle on, go through metamorphosis, and grow. This is typically the reef itself. As the newly settled coral grows, it takes on the appearance of an ice cream cone standing up on its tip. This is a very tiny point of attachment for a coral that's getting larger and larger. At some point, it will break free of the reef. There are many variables that determine where these corals will spend the rest of their lives. The size of the coral when it breaks free, and the speed and direction of the water have a great impact on this. If the coral is relatively small and a large powerful storm moves through, the coral may be washed great distances away and end up in rubble zones, or grass flats. If the coral is growing on the fore reef, it may simply drop to the deep silt beds below. The coral may simply tip over, or fall just a few feet, and spend the rest of its life on the reef itself. This is why we find elegance corals in many different habitats. From clean nutrient poor waters, to turbid muddy environments. Basically anywhere they can hang on and eek out an existence. Even siblings from the same parent coral, may be found in completely different habitats. The growth, and overall health of the coral is influenced by the environment it lives in. This creates corals that may look very different. So different that at one point it was suggested that there were actually two species of "elegance corals". Catalaphyllia jardeni, the larger, faster growing, coral with long tentacles, and Catalaphyllia picteti, the smaller, slower growing, coral with short stubby tentacles. We now know that there is only one species, and the differences are simply environmentally influenced. Due to the wide range of habitats this coral can live in, we can examine individuals from these different habitats and determine what environmental influences enable them to prosper, and what environmental influences cause them to struggle.

If we examine C. jardeni from turbid, nutrient rich environments, like grass flats, rubble zones, or deep silt beds, we typically find skeletons that resemble small flattened cone shapes. These corals typically grow somewhere around 1/4" per year, and have comparatively short tentacles. These are the corals that were once mistakenly refereed to as C. picteti. If we examine corals from more nutrient poor environments, like the reef itself, or near by, we find corals that grow much larger, have meandering skeletons, and long tentacles. These corals typically grow around 1 1/4" per year, or more. Easily four or five times the growth rate of their relatives in more nutrient rich environments.

So, elegance corals are the perfect example to show that stony corals prosper in clean nutrient poor water. Not turbid nutrient rich waters.
