Is This A Safe Decoration

[barb-e]

I have a little coffee mug in my tank as a cave and I was just wondering if it was safe. The mug was bought just for my tank and has never been washed would soap or anything. Is it okay for the water quality or could it affect the ph and stuff like that?

Sounds like its probably ok. If you're not sure, do the vinegar test. It may also be a good idea to boil it before adding it to the tank, just to be on the safe side.

Sounds safe enough!
