Can aquarium snails repair their shells?

What should be done if a snail has huge holes and a damaged snail shell?

First check the water quality: Is the pH 7 or higher? (between 7-8). What about the hardness of the water? (hold up kH and GH). A great way for regulating water quality is to find a source of calcium such asAT nano-carbon. When you are sure that the water quality is good enough to stop further damage, it is up to you to decide whether the shell should be repaired or not. If the snail is active, it can be assumed that the snail will not suffer from the damage.

In such a case, a repair should be viewed as a precautionary measure to prevent other snails from attacking exposed tissue. However, if there aren't any potential tissue eaters like fish and snails, or if the holes are so small that the tissue is inaccessible, then you should leave the snail alone. The snail will calcify the vulnerable tissues in response to exposure to the water. However, if there is a large hole, or if the snail can be eaten alive, the holes can be repaired by gluing pieces or eggshells or even pieces of plastic. The best glue for this is medical super glue or household second glue, but they are toxic until dried. In such a case (household glue) you have to be absolutely sure that the glue does not come into contact with the snail tissue. Holes and damaged areas can be repaired by mending them with strong nail polish (use waterproof varnish), epoxy, or even better, super glue. The latter dries and hardens faster on contact with water.
