i have two amazon sword hybrids, one amazon sword, broad leafed ludwigia, dwarf bacopa, crinium natans, a diffferent species of val ( harder to grow ), and brazillian pennywort. i had 2 36" hagenglo fixtures but, decided i needed only one and gave the other one away. the light is right above the plants and the tank is a tall(2') 65g. i have had the plants for close to a month now
