55g fowlr

[BigHammer]

ive had my mixed 55 set up for 2 years, and over christmas i was lucky enough to get my hands on a led 29g nano cube.

so ive taken all of my coral and transferred them over. whats left is algae, green star polyps, neon goby, blackbar chromis, azure demoiselle, yellow tang, crabs and shrimp.

im looking to add a couple more fish, preferably something that will eat all the mess in there. what are my best options? pygmy angel?

thanks
