PLEASE NOTE: I am on the side of not wanting to hybridize. So maybe someone can explain to this newbie, in terms that are understandable, which of these frogs could hybridize. Since i've been a fishkeeper for many years (okay fine, decades) then perhaps if I put it in terms I understand then someone can explain to me in terms that relate to dart frogs. Okay? So here we go.
Everyone knows what a freshwater angelfish is. Their short scientific name is Pterophyllum scalare, which is of the cichlidae family. Now we have a discus, King of the Aquarium some call them. They are also of the family cichlidae. Both of these particular fish come in many, many colors, patterns and in the angels, finnage (such as veils). They are often linebred specifically for these traits. I personally have angelfish specifically bred from the Philippine Blue Gene (Ken Kennedy & Neil Oyama's lines) and they are absolutely stunning. So I know that if I put a let's say regular silver angelfish I got at PetSmart
(I wouldn't but let's just say I did, PetSmart has sickly fish overall.) But if I put them together they would breed. Nobody anywhere would have a problem with it. Well Ken and Neil might feel ill but...
Discus as well, many colors and patterns. Some specific lines very sought after and quite expensive. Again you could throw any two opposite sex discus in a tank and they would breed. Right?
However, if I put a discus and an angelfish together in an aquarium they would not (could not) crossbreed, even though both are of the same family -- cichlidae.
Now I get lost in the taxonomy trees on frogs:
Family: Dendrobatidae (183 sp.)
Subfamily: Colostethinae (67 sp.)
Subfamily: Dendrobatinae (55 sp.)
Subfamily: Hyloxalinae (59 sp.)
Now is where I get really confused. If we go to: http://amphibiaweb.org/lists/Dendrobatidae.shtml
Subfamily Dendrobatinae (42 species)
In these subfamilies we find: Genus Dendrobates (5 species) [subfamily Dendrobatinae]
Then we have the Genus Oophaga (9 species) [subfamily Dendrobatinae]
And of course there are other subfamilies as well, you all know them much better than I but there are two examples anyway (like my angelfish and discus). It would follow then that if I got Dendrobates auratus and Dendrobates leucom they could crossbreed, right? Now, if I got a tinctorius and a pumilio then would they (could they?) crossbreed? Or would they be like my fish? It's really confusing to have a subfamily with the same scientific name as the family.
Okay, now my head really hurts! Sorting through this is so confusing
Does this make sense to someone? Anyone?
