dang, I love that second one!
The other is in rough shape. I have a lobo I have been trying to bring back from a similar condition with little luck. The only luck for me is that it hasnt died. It has been shriveled like yours for 6-7 months. It won’t get better but it won’t die. I’ve moved it to low light and low flow. My only issue is that I have read you need to really feed these to get them to come back. The problem is that it does put out feeders on all 3 mouths but doesn’t eat fast enough to not get robbed by shrimp/crabs/nassirus. I’m working on the feeding issue to give this another try.
Also I would suggest cutting off all the exposed pointy skeleton spikes as it will be really tough for the tissue to grow back over it.
