Growth or problem

[Mark...]

Coral being my weak link in salt water aquariums, I need to ask a question. Is the edges of this coral a problem or new growth. Its been in the tank just over a month and shot under moon lights with my S4 phone...

Looks like growth to me. If you can snap a picture when the rest of the lights are on. Many SPS have a different color in the new growth such as tips of SPS.

Thanks, I'll do a full light shot and post it.

Looks like growth, it looks good.

For me anyway when things die they go from the base up and out.

That's growth. See how it's got new ridges in it. It's light in color but will darken with time.

Here is under full lighting...thanks! I wasn't sure if it was bleaching back or growing out. Thanks everyone for the feedback. Still trying to get the coral part down.

Think about leaves on a tree. when they first bud and open they are a very light green. as they mature they darken

When corals bleach, you mentioned bottom to top. Is that a good way to judge vs growth white?

You will know when they start to bleach. when they bleach the skin almost peels right off. it isn't a subtle line between color part of the coral and bleached part. it is very distinct.

Wouldn't bleaching be when the coral loses it's color from excessive light or lack of nutrients / combo of both, vs when skin peels off being STN or RTN?

I looks bleached to me once the skin is gone

 

[dan_k]

Wouldn't STN and RTN still be bleaching? The coral is dying so it's turning white or bleaching

I've bleached many pieces and had them color back up in a few weeks time. You can get sps to lose it's color, turn white, but still have flesh and polyps. That's what I thought bleaching was defined or referred to as. STN and RTN is tissue necrosis whereas bleaching occurs when the zooxanthellae leaves the body.

+1 to this. There is a difference between bleaching a coral and having RTN/STN. Bleaching does not mean tissue necrosis, RTN/STN is tissue necrosis.
