Starting a Marine Tank II

Starting a Marine Tank II

This was the second time we were going for a collection and as you can see we were better prepared (in case you are still wondering look at our brand new fishing boots) for depths up to 50 cm. It was an excellent day (the sun was shinning, no waves and a good temperature of 14 C) and we already had the experience from the previous attempt. Large nets, big buckets and a lot of good will!!!

Johnny and me ready to start.

One of the rock pools where you can find many interesting live creatures. Some of them are suitable for a tank while others are better left alone. You can admire life in situ, there is no reason to over collect things that you are going to kill later.


A small octopus (octopus vulgaris) measuring a mere 10 cm (tentacles included) was soon spotted by Johnny. The octopus was put back in its hiding place under the algae "leaves" and left in peace. You can see its dark red tentacles and the sucking cups. I wonder how many people will respect this creature till it is big enough to make it to the open water.

Walking and searching in less than 30 cm of water, you can find almost everything.


A female Centrolabrus trutta (Atlantic wrasse, "cheilou" in Greek). A 6 cm specimen which might make it in a well planted tank. Definitely not for an experimental tank. Thanks to A. Iliopoulos for identifying the fish.


Even very large fish didn't make it following the extremely cold weather and high winds of the previous days. A moray (either the Mediterranean moray; Muraena helena or the Tiger moray; Enchelycore anatina) was found dead in a rock pool. This specimen had a length of more than 70 cm and had no wounds or other visible signs of a violent death. Thanks to A. Iliopoulos for identifying the fish.
