My two bolts have been ok with tank mates both in 240 (3" to 7") and 4500 gal (7" to the current 10"-11") except each other. I can't recall them bickering with anybody else. But it's one man's experience.

Thats interesting that even in such a large tank you noticed the dominant bolt chase the vulture
I can't recall any current, active, and regular keepers either.
They are not common, rather rarely offered. I've seen them for sale only a few times in the last decade. No other reason for not having them I can think of.
