I don't add any additional fertilizer, the dart frogs in the tank do that for me . The tank is lit with 32 3W LEDs divided across 4 "spotlight" units varying between 6500K and a warmer temperature (don't remember) with quite narrow optics (possibly 40 degrees). There is also a supplemental 24" florescent fixture for the rear. These will all be replaced with a monolithic fixture(s) once I get the prototypes made.
The second Racinaea crispa is blooming, and its spike is even larger than the first's despite being a smaller plant.
The Begonia sp. "Tarapoto" has been cut in half and the top was planted next to the mother. It's putting out very nice growth, and the growth pattern is also quite pleasing. Nice, tight leaf internodes, red margins, and hairy leaves.
I tried very hard not to add additional plants but lost that fight. There were just some bare areas that I got impatient about, and I also wanted to add some more drama with the ledges by planting pendulous orchids. My excuse was that I think there is not enough foliage to coax the frogs to be out more.
Already in spike.
The pendulous plant with the large leaves is the species highlighted.
