Rabbit’s foot fern troubles

My rabbit’s foot fern seems to have taken a sudden decline over the course of a few days. It has began dropping curly brown fronds and looks much thinner and skimpier than it’s usual self. Some of the Greg plant profile is not entirely accurate because I didn’t have the options I needed to describe the situation of this plant. It’s in a bioactive terrarium for a reptile, so glass-sided terrarium with screen top. The substrate consists of a dirt layer, rock and charcoal drainage layer, and hydroponic clay beads at the bottom to control the absorption and re-release of moisture through the substrate. The current temp and humidity of the setup is 70°F and 75%RH. The club mosses and asparagus fern sharing the terrarium all seem to be doing fine. Any idea what’s making her so unhappy? #FernFriends #RabbitFootFern #bioactiveterrarium

My biggest concern is probably the lighting then. My rabbit’s foot fern got bright shade outdoors all summer, including about an hour of morning sun, and seemed to do really well. Grow lights seem really bright indoors, but compared to outdoor light, they’re really pretty dim. I’d try to get a grow light closer to your fern if possible.

It’s also possible that it’s being trampled a bit. I had some trouble with that with a Monstera adansonii with my crested gecko. It worked all right when she was a hatchling, but as she grew, the plant started getting crushed. The fact that the asparagus fern is still doing well makes me think that maybe trampling isn’t the problem, but it’s worth considering.

One last thought: are you feeding live insects? I’ve had trouble in the past with crickets chewing on succulents in my leo enclosure. They didn’t live long, but enough damage was done to kill the succulents.
What kind of reptile is in with it? Do you have any standing water in your false bottom? What sort of lighting and where is it relative to your fern? Also, is the soil wet, or does it dry out somewhat between watering?
@ESylvanus A crocodile skink. No standing water in the bottom - an under-tank heating pad turns most of the drained water to vapor, and all the rest is absorbed by the clay balls to be slowly re-released. It does definitely dry out between watering, though the humidity remains high because croc skinks do best with ~70% humidity at all times. The lowest it really gets is 60-65. The tank is <3 feet from a shaded south-facing window, which doesn’t provide much light, but there are grow lights nearby (though not overhead) that provide some indirect lighting, comparable to that of a shaded or part-shade space.
@ESylvanus I think that lightning may definitely be the problem, then. I don’t think it’s trampling because he’s really quite reclusive and prefers to spend much of his time beneath objects (cork bark, water dishes, leaf litter, etc) rather than tromping around on top of the leaf litter and plants. There are is a small isopod population in the enclosure to clean up any dead plant material, droppings, and other debris, as well as springtails, but those feed only on mold and other fungi. He is fed live mealworms and other small critters outside of his enclosure. I’ll try to improve the lighting situation and see if that helps. Thanks!
@Crvidae Awesome! And I’d love to see photos if you have any 😄
