Sarah, your tank is a mature tank. Lots of rockwork. I think you could attempt a mandarin. I like the pschedelic's, but the spotted are nice looking too. From your fish list, I don't see any that will compete for pods.

I WOULD ADORE THAT FISH but... well... I dont have any algea. and I dont have any purple coraline. not sure I am ready for it. I have less faith in my tank. I want stick with hearty fish for now.
