beer bottle caps toxic?

[L.BelcherII]

use a wine cork, and sand the outside edges down with some sandpaper.

I think the fact that you have to ask if the cap is toxic is full reason to not put it in the tank. Do you live in a frat house? why would you want a beer bottle in your tank? maybe try an old tire too that might work lots of room for breeding in a tire.

Actually, if you ever get a chance to go collecting in Mexico, beer bottles and tires are the preferred choice of spawning substrates for many fish. Empty oil drums are also favored.

Good luck,

Yea I was a frat boy, and yea i did puke in the aquarium. But thats not where i got the idea. We go on eco dives, where we clean up the bottom of area lakes, i always have mixed feelings doing this cuz yea it looks nicer. But fish, crabs and lots lil creatures are always left homeless.

I ended up dipping the end in a blob of aquarium silicone, that should be safe enough. My critters are feelin the glass big time. Thanks ALL, Hold nothing against xtyson, hes shooting spitballs at a battleship!!

On the shoreline of BC up in Canada here they sink stuff all the time to boost artifical reef growth and to bring in wreck diving tourists
