Thats one of my favorite palythoas.
Sleeper paly is a nickname I gave it and has no actual scientific basis. or credibility for that matter. but I'll tell you why I call it a sleeper. have you ever heard of that term in conjunction with cars? well it means looks stock but is tuned up, so it doesnt look like a fast car but'll blow the doors off most others. the paly under normal light is brown with a barely visible greenish tinge, but once the actinics are on alone "BLAMMM" the color explodes. just thought I would share that.
feed it often and it will spread quickly.
