Yellow Leather
I believe my questions was fairly straight forth.Why are people who have never owned a yellow leather replying ? They read something so ............. NOW THEY THINK they know something ?
Ok, Yellow Toadstool leather corals very common for them to turn brown. I am trying to figure out what others have done either pro or con. I am trying to nail it down to 1. Lighting 2. Height 3. Flow 4. Temperature 4. Salinity 5. High / low nutrients. Hopefully the people with the persistent yellow and the browning yellow can provide some clues. Person with the yellow coals is doing / using. Person with the browning coral is doing /using.Out of those 5 questions either one or all have to be correct. There has to be an answer and a middle ground we are missing. There has to be. IT is something in the tank conditions causing the browning. Possibly other corals in the tank. I watched the most beautiful. The most beautiful yellow I have ever seen with my own eyes slowly darken and become brown. Over time playing with lights etc. it began lighting up quite a bit to a tan color. I sold the toadstool when shutting down the tank. So, what is everyone doing ? We are doing .................... Toadstool turns brown. Or we are doing ...............................Toadstool turns yellow. This information is vital to all who own a yellow leather coral since there is NO concrete information on the internet.

You'll catch more flies with honey.
What is your: 1. Lighting 2. Height 3. Flow 4. Temperature 4. Salinity 5. High / low nutrients. (water chemistry ie. Ca, Alk, Mg, PO4, NO3 etc) Any and all of these will affect the colour, growth and health of a coral. A picture is worth a thousand words. I've had this fiji toadstool for a few years. It looks nice but has been slow to grow. My system is well outlined in one of the links in my signature.

Picture
Either the picture is deceiving or there are some touches of brown in there. Not the BRIGHT Yellow that I have seen in person.
Can you please specify 1. Lighting 2. Height 3. Flow 4. Temperature 4. Salinity 5. High / low nutrients. (water chemistry ie. Ca, Alk, Mg, PO4, NO3 etc)

More information would help. Is it a new coral that is slowly getting darker brown? Did it suddenly get a brown spot one day? Is it an old coral that used to be yellow for years then went brown?
There is no special conditions to make a leather yellow, it either is or isn't. Often times a newly shipped one will appear more vibrant due to stress, and when you take it home and make it happy it will darken to its natural color. Or if it was a nice color for a long time and changed, something has upset it and you need to share test results to figure it out

Mine was marketed as a gold fiji however the only Sarcophyton I've personally seen that was 'yellower' was a newly imported artificially dyed specimen. I'd like to believe this practice is no longer done but I don't know for certain. Zooxanthella is brown. The pigment that coral produce as a 'sunscreen' is coloured and so the shadowed areas of the tissue of coral is typically less vibrant and more brown than the heavily exposed areas.
Anyways: 250W Phenix 14K MH DE in LumenMax Bottom 30x and indirect 78F 1.025 Ca +400ppm Alk 9dkh Mg 1350ppm PO4 and NO3 undetectable with hobby kits but slightly higher than I would like. Quote:

Have you tried positioning it higher or middle and noticed a difference ? Tried different lighting ? Have you noticed anything that makes the Toadstool either lighter or darker ? You have the yellow in the middle so there is no doubt what it is. But the polpys are a tan color almost a light brown. I will give you some more info. on my TRUE VIBRANT yellow toadstool. I was at a store and saw the most white toadstool that I have even seen. There were about 4 of them. I inquired if they were bleached and was told no. I was told they had been in the store about a month and had remained that color. I took the coral home and was disappointed that after a few weeks the while polyps were darkening up. In less then a month the WHITE toadstool became the most BEAUTIFUL VIVID yellow that I have ever seen in person and with my own eyes. As the weeks went on I noticed the yellow browning slightly only to get darker as the days went by. I eventually started playing with lighting and position and was starting to get the tan color back. I sold my aquarium and livestock shortly after. I have talked to the person that bought the toadstool and it never got that yellow back but only a tan color. He gave me a small frag but it just disintegrated after a few short days. Yellow toadstools are not hardy what so ever and will die if you look at it the wrong way. In your picture the darkest areas that was what I was getting back the tan color before I sold everything off. Last edited by mrdss; 09-28-2018 at 01:53 PM.
