So here is my set up:

37 Gallon Tank

• T8 Flouramax Bulb
• Fluval 403 Canister Filter
• Marineland Penguin 100 Filter
• Tahitti Sand Substrate with Root Tabs
• 2 Large pieces of driftwood
• Small flower pot
• Ridge

Fish

• 2 Figure 8 Pufferfish
• 4 Bumblebee Gobies
• 2 Ghost Shrimp

Plants

• Anubus Barter
• Java Fern
• Java Moss
• Crypt Blassi
• Dwarf Sagittaria
• Giant Sagittaria
• Cambomba

The tank has been set up for about 3 months now and stocked for the past month. The salinity is .005 with water changes weekly to every other week. As you see I have two filters in place for the over filtration which is needed for puffer tanks. 

All the fish get along and diet is strictly live or frozen food. The puffers prefer fresh clams, shrimp, and LOVE pest snails. In fact I need to start breeding them.
