Set up is 22cm cube (8.6 inch) or 10.5L (2.8 gals). Has a little aqua one 100 hang on filter which has a 180L/h (47 gal) water flow. I have poly fliter and ceramic noddle in it . Standard desk lamp with a 10w globe from China. Globe is 5 x 2w led with 1 7000k white , 2x 470nm blue and 2x 470nm blue . Globe seems a bit narrow so might need a taller desk lamp. Got little piece of acrylic and bent it over my camp stove after heating up. Used aquarium safe silicone to stick to glass. Built little rock cave over acrylic with entrance to it in the back right and underneath from the front (mirror pic) . Aqua one 10w preset 26c heater under Rock at back. I felt making rock floating makes the tank feel bigger
