My northsea-aquarium contains only fish and animals
that I or playing childern collected on the beach
living on the bottom
The large worms Ragworms and lugworm live
buried in the sand. The ragworm is a predator, hunting for small fish. Plaice and the common shrimpand crab live buried in the sand.
Plaice is just like the ragworm a nightly hunter.
The other inhabitants
The goby lives on the sandbottom,
grass shrimp and the
Pipefish live a hidden live
between the seaweed.
Cleaning the water
Take a look at the protein skimmer to
keep the water clean and have a look at salinity and conductivity
, important measurements for the condition of the north sea-aquarium.
