That's cool, looks like it was a male and female in the photo. Do they normally lay only a pair or do you think there will be more hidden else where in the tank?
Yeah, I bought a trio of a supposed group and unsexed juvie (1.1.1 group) but not seen all 3 in a while. At least I have a sexed pair, that's always the tricky part (my rio branco group of 4 I think is 4 females

)
The lay clutches of 3 - 5 usually (there's 3 tads in that photo), the female will transport them into individual water pools and feed them unfertilised eggs, usually daily, until they morph out as froglets. They can lay multiple clutches, so i'm keeping a close eye on them.
There's a bit more emphasis to breed them as the country they originate from, Panama, have stopped all exports of such livestock - whether that's temporary or permanent only time will tell. But it means increased scarcity.
I would love some Oophaga Histronica or Oophaga Sylvatica for my next tank but they never come up for sale and the prices would be silly anyway (usually £800 + for an unsexed pair), with them it's now what you know, it's who you know and your level of experience (most are in Europe and US only).
