Ended up being a great plant
I had this temple for over 6 months, first few months it didnt do much, and some fish will eat it. However, if you at least plant some Flourish tabs under the gravel, and use liq fertilizer during water changes, and trace elements once a month. This plant is now almost to the top of the aquarium,and has spread out some. I have a tall 65 gal hex using standard 4bulb 18 inch lamps. 2 coralife 20,000k daylight bulbs, and 2 GE aquarays 9500 k. The hornwort is also doing fabulous now almost 3/4 to top of tank also.
