Looks like I have a nudibranch in my refugium. No idea where he came from. Should I remove him? He is plain black with what looks like a bunch of feathers on his ass. Is this a toxic species?
I have a similar looking nudi in my main tank (Nano). Only seen him at night feeding on the live rock.
Although he has grown in the last week.
No idea how he got in my tank. Hitch-hiked on live rock or corals I put in?
Can anybody give me more info on them.
Good or bad?
