Wich specie can i keep in this terraium (pic)

[Kurt]

Thanks
yes the dendrobate , bombina and agalichnys are in different tanks
which dendrobate for this terrarium(i was thinking in tinctorius)(i only have experience with truncatus(thei are like auratus))

I would immediately seperate these frogs. Bombina are quite toxic and are a temperate zone frog, Agalychnis can be delicate and need good ventilation, and Dendrobates love heavily planted, tropical tanks with high humidity, which can be created by blocking off ventilation. Also dart frogs require smaller prey items than the other two frogs.

That being said the truncatus should get the new tank and I would get a third set up for whomever moves out of the old one. I would not consider any new frogs until these frogs all have their own seperate enclosures and you have established a fourth one.
