Oh the frosting container is perfect, ill have to do some baking today so that I have some empty containers.
This is what I made this morning for their water dishes...the salt water will be the bigger one. I used aquarium silicone (man does it stink up the house) and aquarium rocks.
The reason I left the bottom open is for easier cleaning. Since most things in the water sink to the bottom I wanted to be able to scrub it if necessary.
Would you dig them into the substrate or put them on top of the substrate and build a ramp?
Thanks
