I have a 26 gallon nano reef with two happy clownfish (build thread <--left). Over the next 6 months I'd like to add a cleaner shrimp, a goby, and another small fish--if possible. I have snails that are doing a pretty good job on the sandbed so I could prioritize the small fish over the sand-sifter. The tank has some good places for a smaller fish to hide. My numbers have been stable but the sample period has been short. Is four small fish and a shrimp too much for a tank this size? What small fish/addition strategy should I consider?
