LPS anatomy/growth question

[samuel88]

hi everyone i have a question regarding how LPS grow.

LPSes usually have a skeletal body with the polyps, so when they need to make space for more polyps do they just increase the size of their skeleton? or do they need to be placed near rockwork to spread?

and also another question regarding an Acan i have.

as you can see, the lower left of the acan, if i'm not wrong the polyps have somehow vacated that area perhaps due to fragging or something, i'm not too sure cause i bought it as a frag,

is that spot going to be a 'dead spot' forever? or will the polyps spread over it? or is it not the Acan's skeleton but just rock that the Acan is attached to?

Hi, It still possible grow back under good condition.. It is Acan dead spot or skeleton..

Most LPS can reproduce both sexually and asexually.

Sexual:

In the wild they reproduce sexually by releasing eggs and sperm at the same time, resulting in a fertilized egg which then forms into a free-swimming planula larva. Eventually the planula larvae settles onto the substrate, becoming plankters. This then forms a tiny polyp which begins to excrete calcium carbonate and develops into a coral. Planula larvae are extremely vulnerable to predation, and very few survive.

Asexual:

They use asexual fragmentation, but its success depends on the coral's ability to heal. Propagation can be done by carefully cutting between individual polyps through the very delicate and easy to sever skeletal structure. Make sure the polyps have retreated so as not to accidentally cut the flesh. Glue the frag to a plug or rock. You can use the 2-part epoxy or underwater putties.The slime that the coral will exude should not come in contact with any other corals and gloves are suggested.
