Candy Cane Turning White

[Oneofayykind]

I'm away and have someone feeding for me and watching the tank. I don't have parameters unfortunately. Is it just not eating possibly on those that are turning white? This just started.

How much light are they getting and what type?
That is not from not eating, they do not need to be fed directly. It looks as if it might be beginning to bleach out likely because of lighting or something might be amis with your parms.
I have seen single heads die off while the rest of the colony does fine. They don't appear to be dying however, so just keep an eye on them.

I have a biocube 29g so it's the lights in that and both lights go on at the same time for 10 hours.

Are the bulbs new?
There is a good chance they might be needing more light..

The tank is 2 months old. Do lights need to be replaced that often? Also no fish in the tank for the last 3 weeks or so.

 

[Reeferdood]

No,
Lights usually last @ 8 months but bio cubes usually come with small lights not sufficient for most corals.

So my biocube doesn't have powerful enough lights for my candy cane?

 

[Reeferdood]

Hard to truly answer that without a par meter. Most bio cubes that I have seen are using upgraded lighting and not the hoods that come with them..

Your biocube should have strong enough lights for most LPS corals and softies. I would try and check your parameters. I used to have nanocubes and biocubes running their stock lights and those things can trap quite a bit of heat so I would check your temps as well.
Also make sure you have the correct bulbs. I know with Nanocubes there were models that are set up for freshwater and marine

Getting worse still. Think it's too high in the tank?
