Collection trip – Swedish west coast

The cold does not prevent the collection of new creatures for the tank. The first free dive this year was a good opportunity to collect sugar kelp, snails, spider crabs  and hermit crabs for the tank. My dive buddy was lucky enough to catch a Fivebeard rockling. The trip went to Hamburgsund on the swedish west coast. The sandy bays and rock shores are fantastic dive sites and during night the rocks are crawling with crustaceans. In the shallows you meet flatfish and seatrout. Unfortunately I had some technical issues with the underwater camera, so I did not get as many photos as I hoped, but here are some of them.

On a more depressing note, the trip really showed how we are slowly  destroying the ocean with plastics. The winter storms has carried tonnes of waste to the beaches.

Coldwater saltwater aquarium the critters

When I set the new aquarium the main purpose whas to finally be able to hide all the filterssystems, to be able to add new filter more easily, up the water volumen and thereby being able to keep bigger og more fish.

Since I set up the new aquarium in the begining of winter, I haven´t been able to collect new inhabitants for the aquarium, there isn´t much to catch on the coast during winter. All the inhabitants have been moved from the old aquarium. My favourites are the two cod´s about 10 cm´s long. They eat everything (including my fingers). I think they are the reason most of the hermit crabs are gone.

I also have a Turbot, two Shorthorn sculpin, one Hooknose (the sea anemone ate the other two), and a gunnel. Here is a picture of the anemone just after it ate one of the hooknoses.

I have a few invertebrates, one hermitcrab, a few topsnails, black brittle stars and common brittle stars. I have four different species of anemones (plumose anemone, beadlet anemone , northern red anemone and little brown unknown species).
