After 15 years in this hobby no day alike I find myself yet again in a stranger situation than the day before lol to make a long story short I had a 10-12 inch long snowflake eel in my 400 gallon well established reef who has been on the decline after an unfortunate accident of breaking her jaw. Now I find myself in a position where I believe her to be dead, but in one of many Burroughs under 450 pounds of live rock in Coral. I would appreciate if I can get some opinions and feedback on a course of action whether to leave it and let the cleanup crew take care of it or try to somehow get her out, but that would most likely entail, destroying the entire reef. Thank you in advance.
