I can no longer keep a harem of Royal Gramma's because of my dottybacks.
Just a thought.
We don't have a problem keeping two dottybacks in a 75. We have a strawberry and a diadema.
Any combination of Strawberry, Royal, diadema, or orchid sized similarly and added at the same time works fine with enough rock work and at least a four foot long tank.
But not with Royal Gramma's or black cap basslets.
The black cap basslets would be pretty and less likely to kill each other.
