I've had one in a 32gal Biocube for a year, and have not had any issues with it. It lives with two mismatched clowns (one misbar ocellaris and one black ocellaris), a sarin shrimp, and CUC. Being a Biocube, there's a cover, so jumping's not an issue. It's still about 2-3" long and really hasn't grown. The plan has been that once this tank becomes too small, I'll move it downstairs to the 300gal reef I have.
