Black shade

[ElitePirate]

Hi guys

Ever since I started feeding reef-roids I can see a black shade kinda thing. Never had this problem with coral frenzy liquid food.

Is this normal? It will be ok after a while or?

Thanks

"... black shade kinda thing." Seriously?

What the heck do you mean by a black shade kinda thing? On the back of the clowns? On the rocks? On the corals?

Just adding here incase my initial post is not that clear. I'm talking about my coral. It used to be fully green when it's open. As you can see n the photos zoas started developing a black shade. The photo is not that clear but in real can see it very clearly.

Is it possible that they've moved a little bit on their own? It looks like shading from the little protrusion in the center. I'm thinking that most of the paly gets full light intensity and the little dark shaded spots are literally shaded by that little center protrusion. I have a very similar paly and notice a tiny little dark area where they are angled away from the light.

My experience with reef-roids has been nothing but positive. Is it possible you noticing the dark shaded area when you started reef-roids is just a coincidence?

I don't see the shading you are talking about. Are you saying the palys have lost some color? If that is what you are referring to then it would appear they are in low light. This is from the fact they are extending upwards.

color is a tricky thing. Usually, when colors getting muted to brown it's a sign that the balance of food source in the coral is shifting to the zooxanthellae (more photosynthesis). Thus, I wouldn't rule out that there is something in the liquid feed that us helping color that may not be in reef roids or in a form that your corals can consume.

Only way to find out is to switch back and see if the colors return.

Fwiw, IME my corals perk up with reef roids.

I apologize for being a bit short with you. I wasn't even aware your post was in the zoa forum as I was picking up your thread from a list of previously unanswered threads I have access to. That's my not paying enough attention to the details.

I hope you find an answer to your problem.

Thank you very much guys for all those valuable input

Thank you very much guys for all those valuable input. Yes, I also read a lot of good things about reef-roids thats why i switched to them.

@Justin Cook yes i could be just a coincident. Will monitor
@DSC reef thank you
@erk if you take a closer look at pic 2 you will see the shade. I will reupload another pic.
@NS Mike D thank you.
@Ron Reefman that's alright. Sorry for being short tempered. You're a valuable member and I should have given you more respect so I do apologize

I wouldn't call that black shading. That is just the result of the red not coming out in the blue light because there isn't any red light available. It is probably more accurate to say the palys are losing their green florescence. This could be from an excess of nutrients(doubt it, palys aren't SPS, they like "dirty" water) or incorrect lighting. I can't tell too well, but the palys appear to be extended and are fairly large. This could imply they aren't getting enough light. I honestly wouldn't worry too much. They are healthy and for now I would just observe. We tend to mess things up when we nit pick these little things.

ElitePirate, now that we've cleared up what we are looking at and looking for... maybe a photo taken when the tank is under normal white or daylight conditions.

My other thought is rather than the food being the cause of some change, corals do morph and do so primarily due to changes in light. I have collected wild green zoas from the Florida Keys while snorkeling. I put two frags into my tank, one up high on the rocks getting serious amount of PAR and the other down near the sand. The ones down low look just like they did when we collected them, green face with a dark green pair of 'spokes' on the face. The other ones have turned a dark sky blue (like the sky with good polarized sun glasses). That colony got big and I fragged some for a friend. He put them in a lower PAR area in his tank in over about 4 to 6 weeks they went back to green with 2 spokes!

Thanks for the explanation @Ron Reefman

Managed to take a photo with white light on. Still the pic is not that clear i always kept my zoas up high on the rocks. Also im using Kessil A80 light.

It's not a big issue actually, its just i was bit worried coz last time he had only green and dark green shades. They look healthy so im ok for now. Just wanted to know if i should dose any other supplement or not.
