Can i use household silicone in my fish tank or do i use something else

Question

i have a fire bellied newt and a goldfish in the tank and i want to create a half land half water tank for the newt will the silicone harm them?

Answer 1

Silicone is the least of your worries after the goldfish's ammonia poisons the newt or the newt tries to eat the goldfish or vice versa.  

Answer 2

You need to get aquarium sealer and make sure you let it cure.  One goldfish requires a 20 gallon tank as well.

Answer 3

No, it's fine, but make sure it's completely dry before re-introducing the fish to the tank...if not the vapor could cause harm, but it's pretty inert once it's fully dried (about 24-48 hrs)

Answer 4

Nope...the silicone you use should be absolutely aquarium safe..it should be written on its pack...if its not written then its not safe..get only aquarium safe silicone..and let it dry for a good 5-6 days in the sun before introducing fish..or else it can kill them..
