Seen this on my glass this morning.
Looks like a Nudibranch is it ? Big one.

Great ! So I bought some 6 to put in my 30g that has bad aptasi and it's been 2 weeks and don't see any of them I wake up and on my 120g with zero issues I have this one that must have been a hitch a ride on the LR and after 5 months shows its self. Compared to the ones I bought this one is really big and they move fast.
