I’m trying to figure out a cuc for my new 55gal reef tank. Just got it set up and salt added today. I know I’d like to get a tuxedo urchin and some Nassarius snails. I’m open to any other cuc. How many of each would I need. Suggestions please!
I would let it mature a little before putting in cuc. Let a little algae develope so they have something to eat. Astrea, cerith, trochus and margarite snails work well. They have different focus on what they prefer to eat. Good to have a variety. Put in 10 or so, wait to see how well they are keeping up and as more as needed. They will multiply to match the demand after a while. Hermit crabs are good. I have heard don't mix the different color legged ones. Supposedly the don't get along to well.
