what size tank are these going in? i usually dont like to mix tangs with the same body style like the goldrim/powder blue and the yellow/purple, not saying it cant be done but they can be difficult to mix sometimes.
Going into a 200 gallon.
Knew it could be an issue from the get-go and have had a second QT tank ready to go to split up if needed. But I'm not exaggerating when I say there has been next to no aggression.
