Betta Large Grey Pebble Stack will look at home in tropical community aquariums, Goldfish tanks, cichlid aquaria, as well as amphibian set-ups with turtles/terrapins and other creatures. A few hidey holes are also within some of the pebbles making this a very useful and attractive ornament. Approximate dimensions: 15cm (w) x 19.5cm (h) x 14.5cm (d).
