I'm also looking to set up an opae ulae tank for my parents, have to really get working on the cleaning/decontaminating of the tank we will be using. Found somebody selling opae ulaes on craigslist in my area, and bought a -beautiful- set of corals (also on craigslist) for $25. My LFS also has that macroalgae in their live rock tub so will be adding some of it into the tank.
30 gal planted, tiger barbs, neon tetras, dojo loaches
8 gal Fluval planted: endlers livebearers, amano
8 gal Fluval: upcoming, Opae Ulae shrimp
10 gal planted: endlers livebearers
