Ok, so this is really a two-in-one problem. My first problem is that I'm worried that my Capensis 'red' might be dying slowly (LOL). I found two new leaves, not even fully open yet, beginning to turn black at the tips. I've heard that the 'red' variety needs more heat and all that, so is having temps that practically never goes into 75 good for it? Also, how it opens its leaves changes sometimes. Here's an example (sorry if it's bad, took me 2 minutes, lol)
The one on the left is what I suppose is the normal way because when the tentacle is out and ready, it readily produces dew. However, the one of the right, even when the tentacles are ready, it takes a day or two for it to start making dew.
Now my second problem, I am thinking of changing my lights for the tank completely. I am thinking if I should get 18" T8s specifically for plants and aquariums, or 9" T5s. The width is 20 1/2" while the length is 11". The problem is is that the temps might change dramatically and I'm worried about my Ceph, being a sensitive plant. The tank is 10 gallons and if anyone knows how many of the two I need, or even the temps, that will help. Anyways, since Cephs usually need a drop at night in the 60s, that might change. I have a P. primuliflora, U. dichotoma and U. bisquamata, N. ventricosa 'red', D. capensis 'red', and the Ceph. Any advice would help, thanks.
