I'm currently looking at the fish I want for my first tank. I will (hopefully) have my 75g tank set up as a reef tank. I plan to hook up a 30g sump with a separate, 20g refugium visible in my custom stand to use as an educational tool. I went through and tried to stick with easy to moderate to take care of fish which are reef safe, and this is the list I came up with. Here's what I came up with: Long Tentacle Anemone Ocellaris Clownfish Sailfin Blenny Kaudern's Cardinalfish Longspine Urchin Lettuce Sea Slug Royal Gamma Basslet Yellowhead Jawfish Exquisite Fairy Wrasse Neon Blue Goby Scarlet Cleaner Shrimp One spot Foxface If possible, I'd love to have a snowflake eel. I know this may not be possible, as I have mainly peaceful fish on the above list and most are fairly tiny. I'd also like a starfish, but am not sure if my tank can handle added that to the bio load. The tank will be set in a biology classroom, so I tried to pick some things with symbiotic relationships to show during those parts of the year. I also know the kids would love the uniqueness of an eel and a starfish, and that added diversity would be good for a classification unit. I also did not include the various small inverts that come in the "cleaning crew" kits I have been reading about. I'm not sure how to judge the numbers of fish in my tank. Any recommendations would be very helpful. One area I really want multiples of is with the clown fish, as I picked the specific anemone and clown fish based on the natural pairings in the wild and would like to be able to show the paired fish in the anemone.
