HELP! Something eating my yuma

[mr_cali]

Hi guys. So I woke up this morning and saw some nudibranch looking pests on my yumas. Here are some pictures. they are on the left side of the pink yuma and there are also some on the orange yuma. As you can see, the right part of pink yuma looks like it has already been eaten a bit. Both yumas seem a bit smaller as well. So far, I removed most of "pests" with tweezers and my turkey baster. Should I dip? If so, what should I dip? Any IDs on the pest? Thanks in advance

Anybody? is it okay to iodine dip yumas?

It does not look like a nudi to me... It looks like the insides... could the yuma have gotten ripped or torn?

[mr_cali]

Yeah, it looks like I might have something in my tank bothering it :/ thanks for the input.

How's it looking now? Any changes?

You have any shrimp in with them?

Yeah, those are mesentary (digestive) filaments. Just leave them alone for now and make sure nothing is picking a them.
