Aquarium Species
an annotated list of temperate marine species
Update 2014: the aquriums have been discontinued!
By Dr J Floor Anthoni, 2005
The Seafriends aquarium ecosystems are small and suffer by hindsight from some design limitations such as lack of light. Because of this it is limited as to the number of species it can show and how large individual fish are. For practical reasons, those species that are difficult to keep or that are rather destructive to others, have been excluded. Furthermore, the aquariums are now being prograded to the highest level we can attain, enabling more sensitive species to live and grow. They have become an important part of our research in understanding the nature and workings of degradation, now the foremost threat to the sea. This annotated species list is interesting because it details our experience, good and bad. The Seafriends aquariums have always enjoyed intense interest because of its large number of species, kept harmoniously inside a true ecosystem.

By having a tank for each habitat type, the number of species that can be kept together in harmony is highest. Each habitat has the kind of sand that is found there and also the kinds of rock. Rocks have been arranged to provide shelter on various levels: in the sand, on top of the sand and higher still. They and the plants have been arranged such that territorial boundaries can be recognised easily. In this chapter we'll summarise all visible species that have been kept more or less successfully, together with a description of behaviour and problems associated with keeping them.
Some species provide valuable services such as habitat cleaning and grooming, and they have been placed also in habitats where they are normally not common. Typical of these are sea cucumbers, cushion stars, various grazing snails, hermit crabs and sometimes sea urchins.
