Back into the vivarium game

Hello dendroboarders, after a year disappearing, I’m back into the vivarium building and this time, I’m getting a dart frog. Already build a viv, so many questions and having a problem to solve before getting one in, but first I’ll share my build journey.
I’m to planning to get either a tinc. azureus or an oyapok
This probably will be a long post.

THE BUILD
About 2 months ago i already buying things to build the vivarium. I’m reusing the 18 cube since thats the very bare minimum for getting a dart frog from what i research in here and planning getting only one frog.


To fill the negative space, i found this driftwood which have a unique shape like ramp for frogs to climb. I want to maximize the floor space and the driftwood cover around 5 percent

For background, i use tree fern panels, quite ugly but easily apply than using a sprayfoam and carve and putting silicone

This is my hardscape at its best but decided to not use the driftwood on the left side because I accidentally drop it and break it into pieces.


Completed vivarium and planted 2 weeks ago
Plants in:
Philodendron “malay gold”
Neoregelia fireball
Monstera adansonii
Raphidophora tetrasperma

This is the vivarium 2 weeks after. I have a feeling that the Raphidophora need to get out and replace it with either another monstera or the malay gold or just the simple pothos.

The viv consists :-
-18 cube exo terra
-Modified top screen, change it with glass top, 1 inch front and 1inch rear.
-Lighting, I’m using a standard 2x aquarium led light

• 1.5 inch drainage layer with a pipe to drain water at front
• 1 inch substrate, gradually slope to the back
• thick layer of durian leaf litter, boiled and sanitize.
• A misting system, set to 20 sec mist with 6 hour interval.

-A coco hut under the driftwood ( the tetrasperma was so big it blocked it in the picture.)
- Seeded with springtails.

Questions:-
1. Should i reduce the lighting to one led light?, since i feel like its too bright.

2. Supplement
Is the exo terra calcium + d3 good for dart frogs?.
I read that the repashy calci plus is great standalone supplement, if so can i use this as the only supplement?.

3. Feeding
How frequent you guys feed them?.
Is it ok to feed them once a week?.

Problems I’m facing
Right now, Malaysia is under a deadly heatwave, the temp in the vivarium is 34 to 36 celsius at day and and constant 34c at night ( about above 90 degrees) which in my understanding, deadly to dart frogs in a long term. Is standing fan enough to cooldown the vivarium or should i invest a computer fan to cool the viv.
