The cave marble fits well in my 20-gallon tank. My neon tetras use it to hide during the day, and it looks natural. Easy to clean with a sponge brush. No fish have shown signs of stress since adding it.

I stacked two caves together and it created a nice structure. My guppies enjoy exploring the openings. The material feels sturdy and doesn’t chip or break after a week of use.

Great addition to my freshwater setup. The smooth openings allow fish to swim through freely. It looks realistic and enhances the tank’s natural feel without any issues.
