Default Orchids and frogs - South American build; Madagascar build.

I’m just starting to set up a vivarium and planning on putting d azureus in there, so focusing on the South American montane orchid species, especially Masdevallias (othello, veitchiana, and tovarensis, which I have been raising and are doing well in terms of new leaves and roots). I also have a ceratostylis eria and bulbophyllum thaiorum that I think will like it in there. Will fill with moss, broms and piper/peperomia and other geographically appropriate herbs (I have some small diffenbachia I just cut and am propagating). They should all like the 65-68 winter and 72-78 summer temps in the house here in the PNW (US). Humidity is easy to keep at 80-100% RH with a mister and a little tabletop fan.

I have some montane Vietnamese dendrobiums (trantuanii and thinhii) that I think will do well in a vivarium setting but would love to hear other opinions/experience.

I also am planning on setting up a second vivarium with Madagascan orchids and some Mantella in a few months.

1. Is 65-68F too low for the azureus consistently in the wintertime (oct-mar)?

2. I’m hoping to put aerangis punctata, angraecum didieri and a couple other angraecum species in the Madagascar Viv. Will a Madagascar jewel plant (euphorbia) be ok in there with mantella? I know many euphorbs are toxic for people and dogs if ingested. Any other herbs to recommend?

I’m reading through the forums so thank you all for sharing your knowledge!

Also -

I will heat if I have to 🙂

Gonna do a bioactive build (springtails for now)

If I were to put the dendrobium into one of the tanks, should they go in the Madagascar tank or the South American tank?

FYI I used to be a tropical forest biologist and whil I worked in Central and South America and Malaysia (peninsular and Borneo) and central Africa, I never made it to Madagascar. So while I have very good ideas about habitat and species (at least to genera) for plants to look for to use in my vivs for all those regions, I don’t know for Madagascar, hence the questions —

That may be too high. Shoot for between 70 and 80 percent humidity. If the humidity is too high, the frogs will not be able to properly thermoregulate via evaporative cooling.

Do not allow the temperature to drop much below 69 for extended periods of time. The ideal temperature range for most dendrobatids is between 70F and 80F. The only species that may appreciate that temperature range are certain species from higher altitudes but I won't even mention them as you're just starting out.

I am not much of a botanist so I will leave your plant questions for the plant experts.

I’m not sure the Masd veitchiana would like a terrarium. In my experience trying to grow it in a cool greenhouse it can get be temperamental about heat. It and Bulb thaiorum or even Den trantuanii for that matter are not representative of the same culture. I think the other two would do better and likely flower easier than veitchiana. I encourage you to at least try it out.

In your Madagascan biotope, I don’t think didierii will survive. It is easy to rot. You could probably get away with punctata if it was a spot that dried easily. I took a population from flask and laid them bare root w just some Spanish moss to inhibit too much air flow. Hopefully that gives you an idea of how much it appreciates drying.

Consider Jumellea densifoliata as it has been adaptable to growing wetter than some other Malagasy Angraecoids. Aerangis fastuosa might be another to try.
