Is superglue safe for my aquarium fish? I just bought a castle off of Amazon for my tank and when it arrived, one of the towers were broken. It didn't look that bad so I was thinking I could superglue it back on but wasn't sure whether it would be safe my for my fish
SuperGlue is a cyano-acrylic ester. In the presence of moisture (dampen the parts to be glued), the ester polymerizes to form a solid that bonds the two surfaces together. The reaction takes place almost instantly. Because of the polymerization, there are no residues that can cause toxicity issues in an aquarium.
Cyanoacrylates come in a variety of viscosities. For porous surfaces such as a broken ceramic ornament, the higher viscosity gel products are ideal.
Cyanoacrylate glue (Super Glue) is safe, 100%. Use the gel kind, its way better/easier. DO NOT fall for the stuff the pet shops sell. Same stuff, 3 times as expensive. Its offensive that theyre putting out the same stuff, slapping their name on it and selling it for such a markup.
