Coralline algae die-off

My "monster" BTA decided to spread itself over aquarium side glass instead of on overflow as usual.

When it moved back, a large patch of coralline algae on glass had turned white...next day was gone.

Wondering if anemone caused die-off, or occurred because of temporary loss of light? (rhetorical question)

 

Anemones and reef tanks are a bad mix.. It was not lack of light in just a few days or so. They have a toxin in the pedistal that henders algae and other animal growth from crowding them.

 

Same with corals I guess? Anytime I see a coral growing onto a piece of coralline encrusted liverock or glass, you can see the coralline going white around the edge of the coral growth.

 

I did not know that thanks8)

 

Here's some more info for you about toxicity by corals...you may find it very interesting...

It certainly has changed my plans about how to populate my tank.

 

LOL like a old pine tree nothing but another pine of the same species will ever grow near it, Always a dead ring area around the base of them..
