Hello, I have a 180 gallon tank with a shortbody blue carpentis cichlid about 4 inches and 4 x yellow blood parrots about 2.5 -3 inches and a few blue Botia loaches. I’ve been noticing as they mature there becoming abit more skittish and hiding more than when they were young and more active, i used to have a tinfoil barb in there that used to draw them about abit more but he’s gone now, I wanna introduce some dither fish to maybe draw them out abit more , any suggestions?
