Nice! Always loved jags and always wanted to get a dozen or two to grow out together. Haven't had much luck with keeping mine long term, tried two times with a pair each... but this is personal, not for general reasons as generally they are ok and hardy. Lost the first pair on a 1500 mile move. The second pair quickly contracted some bug in my tanks.
The tank mates should not prey on them or be aggressive as in fighting for the same hidey hole or for feed, or be territorial. Smaller tank mates shouldn't fit in their mouth.
If you wanna see them all the time, lean a flat rock against front glass or place a large rock next to the glass and make it the only cover available:
