| Hello Chris, Do some searches and perusing of posts on this forum. There actually is quite a bit of info if one does the research. But I'll hit your Qs as best I can........ do i need a water feature? No. Pdfs will not make use of a waterfall or stream or deep pool. In fact, a deep pool could actually be the death of a pdf. Water features are used for 2 reasons:
1) to help keep humidity levels up; and
2) aesthetics I also noticed that the plants in a vivarium do better in a viv. with a water feature That can depend in part on the plants in question but basically, no. The light is high enough for the plants And you know this based on what? No offense intended but you have one brom (many of which can survive low light conditions) and moss that isn't growing. What size tank do you have and what is your light source? i havent noticed any moss growing in this tank, the soil is coco-peat and is kept fairly moist. from the stats above, could you reccomend any mosses that would work? What kind of substrate was your moss growing on in the wild? Not all mosses will grow on peat. How long has your moss been in there. Moss does tend to be slow to get going and growing but you light might also be insufficient or other conditions inadequate. Btw, what kind of water are you using? Java moss, though I've never tried it, seems to be used alot in the hobby. I have pillow moss from my local woods, I picked it while it was still alive, and it is not growing Well too late now but you may have introduced unwanted 'critters' to your tank. Hopefully not. would this vivarium be suitable for these dartfrogs At this point I would have to say "No". Such a barren tank will not make for happy pdfs. There's a reason, if you look at pdf set-ups, that they are lushly planted. Pdfs, like most animals, do not like being left so exposed. They need places to 'hide' from you (whom they will very possibly see as a large predator) and from each other (if you have more than one) in order to feel safe and not stress out. |
