If I may imterject, octomush, you sure you want a spanish dancer? It'll need a big tank-afterall, 1ft long, almost constant swimming...Actually they only swim at night or when disturbed. And the largest one ever recorded was less than 1 ft wasnt it?
No! We keep ours in a separate tank. They do seem to be rather delicate and we find the carniverous ones do need sponges as well as anything else we may feed them.Well think of it this way... If u have a large tank 75 gallons or so with lots of rocks since some nudibanchs are so small the cuttles might not even notice them. But most are rather colorful!
