I am very interested in creating a coral reef aquarium, but as someone who has not yet really dealt with saltwater aquariums I am curious what the best type of pets to get for it are? I don’t mind fish, but I am more intrigued by arthropods (especially crustaceans) and cephalopods. I am prepared to do adequate research before purchasing the animals for the reef but knowing a good mix is good to start. I don’t mind investing a bit into it but I would like to keep the daily maintenance costs down, specifically in feeding.
I would like to create a fairly self sustaining environment, but want to be careful to avoid predatory animals that will kill off other species housed with them or compete for the same specific niches (algae eaters, etc.)
Any websites or guides that can provide a good reference on creating a nice balance?
