Came home to my sea hare dead and half it's body missing

[moustachio]

I got this sea hare on Friday from my lfs to combat some hair algae I've been getting and today I came home to half it's body missing(the head half) and the bottom just floating by the sand bed. Now I saw him last night grazing and moving around so I have no idea what could have caused this. Is there any predators to it that I don't know about? And should I do a water change? I don't know if he inked or anything yet. I attached some photos so you can see what I mean.

What other tank inhabitants do you have?

Possible he got into a powerhead?

That is a pretty clean cut/detach tho....

hi, I'm pretty sure it's head just sucked in ,it's a small dolabella, with the split on it's back
seems like was dying before you bought it . JME ...
run some rinsed carbon ,watch params ,should be fine...

I have a dragonet, bi-color blenny, watchman goby, orchid dotty and two green chromis. As far as inverts I have 1 electric blue hermit crab, two black hermit crabs, a blood red shrimp and a pistol shrimp. Besides just some corals so I'm not sure if one of them did him in. Do sea hares invert like that when they die or did he actually get eaten? I don't think he got into a power head cause the tank is pretty clear and the power head have small openings

I'd go with @fishguy242 On this one.

It may have been dying before.

He was pretty big when I got him, I guess that could be the case but it happened so sudden, last night he was grazing and today half his body is left. Should I do a water change? I just did one Friday night before I added him, don't want my fish to die and don't wanna shock my new corals either. What would you do?

 

[fishguy242]

Yes , believe just shrived and died ,sorry
no ink is also a telltale...

Oh ok, thanks that's actually a little bit of a relief for me then, I thought I messed up and did something wrong with that sudden of a death

It's 40 gallon aio, I put a fresh bag of carbon in the back as soon as I saw him dead. Might add another one on the other side of the inlet

 

[fishguy242]

better safe than sorry ,with 40 gallons, I would recommend 4 gal water change.
the one bag of carbon should be enough

Sounds good I'll go ahead and do a change, I really appreciate the help and info
