My CBB doesn’t care about flow, he quite happily plays in it by swimming up and then almost “Giving up” and gliding back. What I’ve found in terms of key to success are;
- Minimal QT
- plenty of good well-established microfauna
- Variety of food
I don’t target feed mine and instead I will spread the food in the middle of the tank and let the pumps deal it between everyone. The fish love it and have a buffet, I’ll also feed some algae and he will peck at it along with the foxface and tang. Their swiming pattern is interesting as when they hunt they will sometimes turn their body upside down to get their nose into a hole in the rock. Here’s mine, the top photo is her hunting and the bottom is her begging/waiting for food.
