Review on 1031 Pk4 Organic Half Shell Coconuts Bonka Bird Toys - Ideal for Natural Foraging, Chewing, and Creative Parrot Macaw African Grey Art & Craft Parties by Jill Smith

Until I cut a hole I never realized how hard and thick a coconut shell is! These are good, clean, uniformly sized bowls large enough for most resident fish, including dwarf cichlids. Mine were darker than pictured and all they needed was a door. For the hole, I drew about a 2 inch flat bottomed circle. I tried a hand saw first but it didn't work so I used a dremel cutting blade, scored it and went over it a few times. Unlike wood, they sink instantly and will likely last forever.
