Mediterranean Sea Tank - December 2019 update

This month I had a chance to pick up some stock from the Mediterranean Sea. I want to mention especially the sea cucumber. Some people are still afraid to keep sea cucumbers, but I think this is a perfect inhabitant for seawater tanks. Because they are the vacuum cleaners of the sea. Who doesn't dream of an animal that sucks up all the dirty sand, digests the debris and leaves clean sand behind? Of course the sea cucumber as any other animal produces nitrates and phosphates, but those are consumed by bacteria, anemones, soft corals and plants. I'm happy that I found one just coincidentally in the shallow water by a port. Isn't it cute...?
