Hi, my name's Javier, I'm from Chile. I bought 4 red cherry shrimp, I made a shrimp tank and this is the design I made. I made it with the rocks and sand that I had, so I tried to make it without buying anything else than the shrimps. I hope you like It :Happy: Tank: 20 liters (40x30x20) Shrimps: 4 neocaridina heteropoda Plants: Cladophora aegagropila Taxiphyllum alternans 'Taiwan Moss' Lighting: 6500K energy saver light bulb (I'm going to change it soon) Filtration: Just a water pump, I'll buy a filter tomorrow. Sorry for the bad photo.
