My powder blue loves the 3,250 gph Hydor 8's which are on each end of my five foot 125 gallon tank. I had a tank crash(the details of which I will not go into) a year ago in my five year plus old tank and lost most of the fish including a 5" powder blue I had for 3 1/2 years. He got along with other tangs although he did not like new fish.
I replaced him with a five inch powder blue six months ago from Dr. Foster and Smith and he seems a bit milder in temperament. I cut my sea weed with scissors into bite size pieces so it can be sprinkled like flake food. My powder blue tang has a smaller mouth and likes to take these pieces soaked in Selcon, Vita-Chem, and Brightwell Vitamin C.
I also feed the tank freeze dried mysis, brine, bloodworms, along with flakes soaked in the vitamins.
Drs. Foster and Smith recommends a 125 gallon for a powder blue tang?
Of course we want to go with the majority and never deviate from the collective knowledge present here.
