Bubble coral

[Fireclown]

I'm unsure whether bubble corals are photosynthetic. Heard of people feeding it with market prawn. I'm wondering whether that's true. Could you guys enlighten me on this?

[FuEl]

They are mainly photosynthetic due to zooxanthellae colonies they house in their tissues. LPS grow relatively slowly. Photosynthesis can only provide them with carbohydrates to sustain metabolic functions. For growth they will need a source of protein. Hence any form of protein like mysis shrimp will aid in growth. You don't have to feed them protein very often since they grow so slowly...feeding once every 7-10 days should suffice.

Relised that tenticles are extended when the lights are off. Are they feeding? Mine is the white branch bubbles.

[blacknails]

Yeah.. With their tentacles out at night they are trying to catch food.. you can drop a few mysis shrimp on the coral and see how it directs them into its central mouth..

But beware though as the tentacles may go on to sting other corals if they can reach..

does that mean we shld feed it market prawn only at night?

[FuEl]

Most corals feed on zooplankton during the night as they are more plentiful during that time as they rise from the depths. That's why you normally see sun corals opening at night in the wild.. LPS will then also reveal their tentacles for prey capture. Feeding on zooplankton at night might also be due to the amount of fishes during the day...which could compete with them for food and also attack their polyps.

i use to dose zooplankton 2-3times per wk,am i suppose to dose it after lights are off?

Oh, I just remembered, there is a 3rd species in the plerogyra genus, Plerogyra discus (spelling?). It looks more like a fox coral than our idea of a bubble. There should be a websearch url somewhere, but I cannot recall the url. Anyone?
