Will this kill my fish??

will superglue (krazy glue and cvs stuff) kill my fish if i put it in the tank with them, i used it to superglue peices of a terra cottapot that fell, i broke it on purpose, to put half in the tank for the fish to swim through and hide in, but it broke too much, so i glued it with superglue and let it dry.will it hurt my fish if i put it in the tank? btw, the tank i want to put it in is a 30 gallon with 2 electric yellow cichlids and a kenyii.
