The cobalt blue color is stunning and the fish are active but not aggressive. I added them to a 10-gallon tank with live plants and they’ve settled in well. They enjoy the hiding spots and seem happy.

Beautiful fish with vibrant colors. They do need some space and hiding places. I made sure to include driftwood and java ferns. They’ve been peaceful since introduction.
