I totally agree. I tend to be drawn to bottom dwellers so all my tanks end up at capacity on the lower levels and I'm left trying to fill the top of the tank with compatible fish. And a lot of bottom dwellers are fairly lazy, at least during the day, so the middle and top dwellers add some color and movement. I'm currently still adding to my Poly tank, but really like those pearsei, will probably consider them down the road.As much as I like my polys, I still want upper movement in the tank. A lot of cichlids out there completely ignore bichir but you never know, you may get that one odd ball the is super territorial and hurt a poly. Pretty safe bet with bocourti and pearsei, though I saw a pretty big jag and ornate sharing a tank before with no issues.
