I have some cyanoacrylate glue that I want to use to glue some corals. Can I use the glue when it hasn’t cured the recommended 24 hours underwater with fish in the tank. Is it poisonous when not cured for 24 hours. If it is then how to I glue my corals down. Does the glue even have to be cured? It is fine so long as it’s dry to the touch?
