I've just got into marine aquaria again having left off twenty odd
years ago. Things have changed on the equipment front in the past few
years.

I set up a small tank as an experiment and filled it with beadlet and
plumose anemonies and some Sagartia species, a clump of peacock fan
worms and a shanny and some starfish and of course some (small)
crabs. It has been going for six weeks now and seems to be ok.

It is hard to find anyone else who keeps cold saltwater aquaria, this
forum doesn't seem to be active at the moment, Is that true?
