Need Help with Shrinking Orange Yuma Mushroom Coral issue

[dwc72890]

Hello everyone,



I'm reaching out to seek advice on an issue I'm facing with one of my Yuma mushroom corals. Recently, my orange Yuma has started to shrink noticeably over the past week. I've tried relocating it within the tank, but there hasn't been any improvement. Interestingly, the green Yuma in the same tank is thriving.



Here's a summary of my tank conditions:

- **Size**: 13.5 gallons

- **Lighting**: AI Prime HD16 set at 60%, running for 10 hours per day

- **Water Parameters**:

- **NO3**: 0 ppm

- **PO4**: 0.01 ppm

- **Salinity**: 1.025

- **KH**: 7.7 dKH



All my other corals are doing fine under these conditions.



I'm attaching a picture of both the green and orange Yuma for reference. The green one is doing great, but as you can see, the orange one is not. Any thoughts or suggestions on what might be causing this issue and how to address it would be greatly appreciated!

Chemical warfare?

Are you running carbon to filter out the chemicals that the coral can release?

Yes， I have put a bag of carbon in the filter

try dosing nitrate and phosphate. I use neophos and neonitro. could help. I keep nitrate 2-5 and phos around 0.03

Thank you, I don’t really have those in hands . Can I maybe feed the fish a bit more food to increase the No3 and po4?

It might. Amazon has both of those. They work great. start at a low dose and titrate up until you reach your goal. I usually dosed them twice a week.

IMO nutrients are low. I’d target feed with reef roids/benereef, mushrooms are little pigs and love nutrients/eating.

Also, your lighting in that spot might be too bright for the orange mushrooms’ preference. What % do you have the cool white set to in the AI app?

I agree with the light issue. I actually use high lights to suppress their growth since I have so many. Once they get going they can really take off. Of all my ricordia the orange have grown the fastest. I started with one and now have over a dozen. Be sure to put it on a rock island of some sort.

Here is my light setting .for the white like I usually set it 10-15%
I have moved it to the other side of the tank which has less light . Will see how it doing tonight when I’m get home .
Thank you for the advice
