I've owned two powder blues in my reefing experience. Previous was about 5.5 inches long and I owned him for about 1 and a half years until a major bacteria outbreak/heat problem this past summer claimed half my livestock ( gotta love it when your AC breaks on a 102 degree day )
PBT #1 - 6 inches
Personality: Non-aggresive, seemed to really just do his own thing during the majority of the day. Was a very light and dainty eater, and would only eat nori/seaweed. Had absolutely no interest in anything else.
Habbits: Would usually swim the length of the tank at a medium pace, and quite often sit 6 inches from my Koralia 4 "surfing" the current. It was quite fun to watch him zip around surfing the tank, they really do like LOTS of water flow when they get older.
Health: I've run both a UV and no UV on the tank for some time while having the fish, Ick was here and there from time to time, the cleaner shimp would usually get it off overnight. I thought my UV was helping but after taking it out, it seems Ick outbreaks are almost entirely based off the overall mood and stress of the fish. Happy, stressfree = Clean, no ick. Stressed / Hungry = ick.
Granted i have no real data to back this up, just something i've noticed
PBT #2 - 3.5 inches
owned this one for about 4 months now, He exhibits some of the same habits my old PBT had, although he's a bit more interested in other types of food. This one has yet to start coasting in the water column around my koralia's - but seems to follow the same ick = stress/hungry signs that my old PBT had.
