Can fish and invertebrates live in the same tank?
It is up to the aquarium owner to decide whether they want to do this. It should be left to the extremely novice, aquarium owners. Although there are a lot of really beautiful reef fish to choose from, some are carnivores and will feed on invertebrates or live coral. Plus, diseases like ich can be very hard to treat since the cell structures between parasites and invertebrates are similar enough that the effective treatments for ich will also kill the invertebrates.
