Can you please help me to identify if these are Dino's and if so what type and how to deal with them? They are mainly on the sand bed and some on the rocks maroon/red-ish, slimy with some bubbles. There seems to be less on the sand at night after lights out and very little show up up on the sand in the morning. Once the light comes on, it seems to blanket the sand.
Thank you in advance.
