I have a 55 gallon established freshwater community aquarium. Recently I decided that I wanted to upgrade by making my own DIY background out of slate floor tiles. I cut a piece of plastic wall paneling to the size of my aquarium and I used that to silicone (100%) the pieces of slate tile to. After I let it cure for a little over 48 hours I put into my aquarium. After this happened, the health of my fish degraded very quickly. My tetras and mollies stayed at the surface and my angel fish sat on the bottom along with both of their activity being cut to a minimum. To ensure that it was actually the background, I took it out. When the fish returned to normal I put the background back in and they returned to their unhealthy states. Does any one know what the problem could be?
