I have a 10 gallon tank that I bought when my son had a snake for a pet. This tank has been unused for 11 years. Are those tanks essentially the same as an aquarium? Is the glass any thinner? If it is water tight, should I remove the aquarium silicone and apply new to seal it? I plan to use it for a hospital tank.

Was it sold as a tank made for reptiles specifically? Many reptile tanks do have thinner glass and cannot hold a full load of water.
