Had my tank for about 4 years now and found the creature in the picture for the first time, I have only added a algae blenny to the tank this year so he must have been in the tank a while and I only spotted it about 3:00am so may be hard to find again!!! Has any one any ideas what it is?? I thought it was a type of flatworm to start, but told it was too big by my lfs, they said it was a nudibranch! But another lfs said it was too big for a nudibranch, and could be a flounder!!!
The rough size of the creature is about 2mm thick, 50mm long and about 35mm wide, it travelled along like a snail any one any ideas?
