Yellow-Tail Damsels

[canadawest]

I have had a single YT Damsel in my 100gal tank for about 18 months now, no problems at all. I actually marvel at how accomodating it is of it's tankmates. Never chases or harrases other fish unless they try to hang out in his hovel.

Bob, what's the reasoning behind not keeping just one?

PS.. It was one of the first tank inhabitants and thus the theory of it establishing territory and taking over is incorrect in this case.
