so im starting up a 30 gallon puffer tank. probably gonna be 2-3 figure 8 puffers in there
so decided to make a 3d background.
used regular white styrofoam and "Behr Basement and Masonry Waterproofing Paint"--- just like drylok
the paint is water based so i figured it would be safe for the fish.
no concrete used at all.
I will probably add darker grey paint to give it more depth
in the middle will be a dark blue background with blue LED
lighting backlighting it.
hole in the rock for the filter intake
inside of the cave where the heater is
Side of the cave where the heater will sit
