Hello, I am brand new to fish keeping and planning on the following combination of fish. The tank is 26 gallons. 5 Zebra Danios 5 Cobra Guppies 3 Leopard Corys I also wanted to add a mystery snail and a filter shrimp or bamboo shrimp. Would the snail and shrimp be overstocking the tank? Any different ideas? I really like the Danios so combos that work them in would be ideal. Thanks for any insight.
