Hi is there any spray paint you can use to color the inside of an acrylic tank(Background) safely if yes what brand and kind is it will it be safe for the fishes Thank's.
no cause mine got a painted blue thing already and I think it was not painted from the back.Bud8Fan;1208454; said:I have been told that the Krylon Fusion paints made for plastics have been used on PVC inside of tanks with no problems. You could try that.
Why can't you just paint the outside of the back?
