The scooter requires a very mature tank so that it can eat
pods, some might eat frozen food from the start but most are like mandarins, they only eat
pods. The butterfly will also give you eating issues, they can be super finicky and dont do very well usually.
The tangs are good, the blue can be a challenge too but 2 tangs in a 6 foot tank is good, you could even add a third tang if your heart desires in my opinion. I kept a blue, yellow and tomini in my 125g for several years and they got fat and happy.
