Is an octopus a plant or a mammal?

That question deserves a poll on its own

I just can't. But I do use Instant Ocean!!

Yes... But only between 5 and 9.

My favourite is the birthing photosynthetic octopus..

Mineral.

And Instant Ocean for the win.

Since the thread is kinda off topic...

and people still smoke at gas stations.

The biggest corals I have grown are a 12" acropora and an 18" x 14" sunset chalice from a piece 2" x 4".

The ocean is a different story. House sized corals can be common. I've seen table acros 10' across.

Smacks head you don't say. We're talking about size of corals in ocean the biggest ever found, you know . Lol

I have a 12"x14" green sinularia in my softie tank. Not the biggest but damn huge.
