Tag Archives: cod


The cod finally got to big for the aquarium – mostly because it eats more than the filters can handle. The two sculpins where put back into the ocean.

Instead I caught a lumpsucker, shrimps and thousands of mysis to feed the shark babies. I now have three newly hatched sharks and a small Greater weever.

Below are pictures form my collection trip when I caught the Greater weever and msyis caught during a night dive. Mysis gets attracted to the light form the dive torch and are easy to scoop up with fine-mesh net in front of the light.

the perfect food for the coldwater aquarium

On a diving trip too Sweden I stumbled upon the perfect food for the aquarium – tiny herring. They were sold in a supermarket as bait-fish. I have tried using white-fish bought from the aquarium stor before, but they apparently smell wrong, my fish does not react to them. But herring make them crazy. The cod ate 4 in 2 minutes!

Here is “Torben” as we call to most aggresive of my two cods after he swallowed his 4th herring:

The sculpins where not as fast in getting to the herring, but when the hermit crabs started to move them around the sculpin moved in.

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).
