Unique fish for 29 gallon

[Raider0622]

Hey everybody. I know there are loads of threads about fish for a 29 gallon, but they all say the same things. What are some unique fish I could get? I already have a 75 gallon reef tank with clownfish, a goby, and a firefish so those are off the list. I was thinking about getting seahorses or an angler but seahorses are so expensive and getting a good angler is hit or miss. Thank you!
