I want to paint a dark blue or black background on my tank but i'm wondering what kind of acrylic paint I should get? If anyone can give me a few links to sites that sale waterproof acrylic paint & sites showing pics of backgrounds painted on that would be really helpful.
I dont know about water proof, but at almost any craft store you can get paint that works on glass. Though, it would be best for making a kind of stained glass look rather than a solid colored background and should be used on the outside of the tank.
Even if this is to be just a solid color, I would use latex, and apply it in a few coats to make sure you get good coverage. If you decide to experiment with stonework like is shown in the links above, just remember you're painting on glass, so you need to reverse the steps. For instance, if you were painting fake marble, you might do the veins in the marble last, but so they show through the glass and other paint laters, you need to paint them on the aquarium FIRST!
