My 2.5 year old granddaughter Quinn was over tonight and even though I am just starting my tank slowly and have very little in it she was mesmerized by everything. She was calling out it's moving as the hermit crabs were crawling across the sand and wanted to watch the snails on the glass and she loves the few fish I have especially after watching Finding Nemo. It made me so happy to see someone enjoying my tank as much as I do I had to take some pictures and share.
