I've had this yuma for about a week and a half now, it's mouth started getting very large 2-3 days ago. Is this longitudinal fission/splitting, a bacterial infection of some kind or is it dying? Water parameters are perfect, dKh is 9, temp is a steady 79. The yuma has been kept under 36watt Coralife PCs in my 12" cube, it's currently about 3" below the surface. I haven't seen any other tank inhabitants even getting close to the yuma. IDK, all my other corals are great and even my clam (got my PAR 38 yesterday, so no "clam under PCs" bashing please) is happy. I've been doing half gallon water changes every 3 days using Tropic Marin Pro Reef. This is my first and only ricordea in my first and only reef tank, I can't find any answers on the internets, let alone pics that look anything close to this. Any help, suggestions, ideas would be greatly appreciated. Thank you.

I've never had too much luck with yumas as well. From what i've heard from friends you should acclimate it to your light by putting it under a cave or crevice and bringing it out an inch every few days and moving it up very slowly.

I've tried just leaving them at the bottom of the tank under only T5s and they still don't make it sometimes. I've had more luck with sps than yumas.

- also from the pic it looks like it's very stressed and expelled the contents in its stomache, usually when mine get to this point they don't make it - try dropping him to an area with less light. They are pretty low light corals.

Thanks, Amenstia...I'm gonna relocate it. I hope I don't lose it.

Morning Bump!

Individual small pieces are coming off of it now. Is it too far gone now? Would Coral Revive be worth a shot?

same thing happened to mines... and it died. good luck!

only other thing is to leave it be under low light and low flow but not too little or too much that it blows more pieces away

then cross your finger's maybe a small chunck will make it

It doesn't look happy. Get it as shaded as possible and keep your fingers crossed. It's pretty bleached looking, so I'm not too hopeful about it's survival unfortunately. Yumas can be touchy.

My yuma had 3 babies under PC's. Moved him under halides to get better color, we'll see, he changes shape throughout the day.

IME Yumas that get a hole in it, are done....signs are usually, a bleaching....then a gaping mouth, body will seem to get thin, where there seems like wide, flat areas between the bumps. I've had plenty of high dollar yumas melt after a month and up to 6 months in the tank. Currently, I have one true hot pink yuma thats been in my tank for a year and a half...Good luck, but it seems like most super sick looking Yumas end up melting on people. Might be a collection or shipping methods that stress them out.

Thanks for the reply. I've got it shaded in a low flow area, it hasn't gotten any worse. I'm not betting on it making it, but I can't bring myself to give up hope on a $$$ coral like that. After further research it seems the pinks don't do well at all, especially a tank that isn't fully matured. I had no idea varying coloration meant different levels of difficulty. This has definetly been a lesson for me, whether or not it makes it.

Check out this Yuma I got

6 months later, look at how it looks deflated, and how the mouth is gaping...being shaded..BTW, that pink one next to it melted in 3 months...

Here are three more Yumas, two of which died in 10 months....I still have the Pink one on the right, for 1 1/2 years

Here is my only survivor today

I stopped collecting them, because of the failure rate.

Quite the collection, Fishez...I love the survivor. I'm a bit disenchanted with ultra yumas at the moment, mine is all but gone. This is my first livestock loss since I started, it's aggravating because my parameters were great and I haven't been able to find an explanation of why yumas do this. All I've read is that the reds and especially the pinks have horrible survival rates. Is there an explanation I missed or a reason the pinks and reds don't fair well? If I ever work up the nerve to attempt another red or pink it'll be aquacultured and I'll have a bigger, more mature tank.
