Default Are corals really strictly carnivorous?

You are a troll or have completely lost it.

: To be 100% sure of anything about corals is to be a fool.
: Polyps are basically carnivorous, lets say 95%.
: They may feed on algae debris floating around. Their digestive system are
: completely capable of digesting and utilizing some vegetation but is by
: chance not by choice.
: Now, as far as using the zooxantell within, that is impossible. First, the
: algae is not even close to its digestive system, therefor, It can´t be
: digested. Second, the algae produces vegetative living matter out of
: sunlight and incorporates it to its own body which, as I said, is AWAY FROM
: THE DIGESTIVE SYSTEM of the polyp. Third, the algae may and will utilize
: digested residoir from the polyp´s meal after it enters the polyp´s body.
: With those macromolecules the algae produces carbonates that the polyp can
: use for skeleton building.
: Your buddy here tried to say that corals utilized algae for food. That was
: a barbaric statement and I corrected him.
: Enough is enough...

: I don't know how will you understand that corals are CARNIVOROUS and
: don't eat the algae.
:
: Are you 100% sure this statement is correct for ALL known corals ?
:
: And one more thing, how do you define "don't eat the algae" ? Do you
: really mean strict 0% of any coral diet is algae ?
:
: Yes, the algae's, and any plant for that matters,
: production is fixed on its leaves. That is the reason why the coral
: CAN'T benefit from the algae's production.
:
: Even more interesting... Could you please provide me with some paper
: elaborating on this subject ?
:
: Light down there uses no BALLAST OR EXPENSIVE FIXTURES. It is just
: natural sunlight, the same one that can be reproduce in your living room
: with inexpensive lights. Of course, if you want it to look pretty, the
: $500 investment is worst it. But please, don't tell anyone that those
: lights are needed other than for aesthetic purposes'.
:
: Except scientific facilities, most of the fish tanks are kept just
: for the aesthetic purposes, so I am not sure what is the problem...
: The statement about "reproducing sunlight with inexpensive lights"
: is quite peculiar...
