Yep, it's a 6X54-watt Tek. I usually only have either two or four of the lamps switched on.
Really the planting looks pretty crumby right now. You gotta go back to some of the earlier pages for better pictures. I hope that I can get it into better shape soon.
I have the exact same fixture on my 75g but I only run two bulbs at the moment, although I ran all six for a while, a couple hours a day. It's a very robust piece of hardware.
THanks. Over on the right are I think a Ruellia brittoniana and an Asclepias sp., two very easy plants. They both flower readily too if you give them adequate ferts.
interesting. I asked because I thought they were similar to the mexican petunias that you sent me... but mine grow much longer leaves. It's nice how yours stay compact. I'm sure now mine need a bit more light.
The other night I got a bloom from my Traub's spider lily (Hymenocallis traubii). I was so happy to see it open. This one is not currently growing in a riparium, but I did have it in the 120-gallon Mexico semi-biotope last year. I kept the bulbs dormant this winter and they began to grow right away when I potted them up in a terra cotta pot with clay gravel for growing in a container pond.
The foliage is only about 12" tall--many other spider lilies are bigger--so this plant has the right size and shape for growing in a riparium. The flower stalk grew somewhat taller, to about 15".
