Hi There, wondering what the hell this is. Tank is over 6 months old, live rock was all fresh although from couple different places and this is the first time i have seen this. Don't know if i should get it out.

Looks like a nudibranch
Maybe search them on google and have a look at what they eat
From what I have seen its not great having them in reef tanks as they sometimes eat some corals but I'm no expert

Think i may banish him to the sump

Best to just take it out all together
Some are poisonous and if it gets sucked into ur return pump bam-kills everything u will be one sad puppy when u realize haha

On it, Thanks for the advice.

Almost certainly a form of Opisthobranchia mollusc, and may be either a species of Nudibranch (although I cannot see the external gills in the photo provided) or a juvenile sea-hare (family Aplysidae).

Are you able to provide a better photo for identification purposes?

Almost definitely a nudibranch. What kind is anyone's guess ... you could search www.seaslugforum.net , you never know it could be a safe one and pretty cool that it lived 6 months - many live on sponges and so die.

[edit]crap just found out that seaslugforum is no more! Another resource is: http://www.nudibranch.com.au/specieslist.html

Or just get @dr_schell on the case :D
