My 180 has lots of fish, but none that will eat the shrimp. Lots of small gobies, a pair of Argi dwarf angels, pair of sunburst anthias, firefish. Also 2 red shrimp, 2 orange coral banded , 2 cleaner shrimp, sexy shrimp, orange claw scissor shrimp, ghost pipe shrimp.
Also I do have one other anemones, but none available or attractive to the shrimp; A sand anemone hosted by a pair of perculas, and 2 tube anemones.
Just my 2 cents, but jawfish may be a bad idea. Specialized habitat, big mouth, might need larger than a 20 gal.
