Ok I have a question, hopefully someone can help me out
I recently went over to a local craft store and found some really cool glass marbles I would like to put in a tank. They are beige with a shiny glaze over them. My question is a) are these any different then the ones in pet stores and b) how can I tell they are safe for my fish? I'm worried about the shiny glaze part..is there anything I am looking for on the package that would make it not safe for a tank? I THINK I saw on here a while back about putting vinegar on things to see if it foamed for tanks, but not sure. I want to make absolutely sure because I have Bloo coming sometime next week (Thanks Zenandra!!) and possibly my first aquabid fish (if I win him ^^).
Sorry for being such a worry-wart & thanks for your help! :D
