    No. Anything that says mold free or mold resistant is not good for aquariums. Get one that specifically says safe for aquariums. There are few different ones on Amazon for 10-20$.

    You need one that is 100% silicone and has no additives. The thing is, the manufacturers arent required to list this on the package. So you really dont know what is it those, for most applications it wouldnt matter, but for fishtanks (or animals cages) it does. Which is why you are better off spending a few extra dollars and get the stuff meant for the job.

    Only Silicon that is clearly marked and sold as " Aquarium Safe " is non toxic to fish Etc

    Momentive RTV as BDpups suggested is great stuff, easy to work with, and aquarium safe. If you want black, use RTV103 instead of 108.
