Anyone keeping multiple dottybacks in same tank?
I realize some are more aggressive than others, looking at pair of orchids and a sunrise. Tank is a 150g
The size of the tank will help but it can be a problem mixing different types together. At different time Ive keep a pair of Orchid and 2 Sunrise together in a 75 gal tank without any problems. I introduced both fish at the same time and they pretty much kept to themselves. I have had problems trying to put in different dottybacks with the Orchid and even the Sunrise, which has resulted in the new fish being attacked.
Those the Stripe and a one or two others are probably your best bet
One a side note, it's not that easy to find a female Sunrise, so you may have a problem finding a pair but I've kept 2 males together without any problems.
