Impossible to keep... even the experts stay away. Success rate is EXTREMELY low. The foods you are using are good BUT you have to keep a CONSTANT supply of food in the tank... which will cloud the water, and more than likely kill everything else in there due to the over saturation of nutrients. Unfortunately, it’s best to leave these pretty little guys in their natural environments. Best of luck, though, and def keep us posted on your progress... it sure is nice to look at!
