True that McPuff! There are a lot of damsels to choose from. The challenge is finding ones worth keeping!
The first step was to research them and seek out less belligerent species. That got me down to about four or five. Now I'm trying out single specimens in QT to see how they get along with each other. The final step will be to introduce schools of each species to my display, after QT of course. It's a big step! In my experience, schools of fish tend to more concerned with each other, than other species. I'm counting on this, to help keep the peace. I've found that the peaceful species tend to be planktivores, rather than herbivores, which farm patches of algae and can be very territorial. With lots of open water column, I'm hoping there is enough room in my tank to accommodate multiple schools. Also, there have to be enough places to hide for everybody.
I have no idea where this will take me, but I'm enjoying the research. Damsels tick two of my favorite boxes - cheap and sturdy. Great colors, small size and constant activity are also big plusses. Stay tuned"¦
