Dendrodoris elongata in aquaria

March 18, 2004
From: Christian Feiland

I found this in my 240l Seawater aquarium. The live rocks are from the Sea of Marmara (Mediterranean Sea - Turkey)
But I do have rocks from Singapore in my aquarium too. So, I am not sure where the slug is from.
Thanks a lot for your help!

Dear Christian,
This is almost certainly Dendrodoris elongata which is a species from the Indo-West Pacific. The most likely way it got in your aquarium was as a juvenile, hidden in some crevice in your live rock from Singapore. I assume there was some suitable sponge on the rock which has allowed it to feed and grow to its present size. The other alternative is that it, or its parents, came as a larvae from the Red Sea via the Suez Canal [see page on Lessepsian migrants] and settled on a rock in the Sea of Marmara.
Best wishes
