Who can give me a picture of the apisto sp D50

[crouns]

A fish trader told me he got some WC Apisto sp.D50,but I cannot find any information and picture about this fish online,so I hope I can get this information from here.

I know of only one person who has them, Erik Paul.

Here's a video:

This is a species that Oliver Lucanus (Below Water) sold as A. cf. helkeri. Check under that name, too.

I have a few photos of the Apistogramma sp. "D50" (Alto Vaupés II) at my site, too...

I saw a discussion on facebook between Frank Hättich, Roland Kipper and Erik Paul where they were discussing whether D50 was the same as D10 and it basically was a splitter vs lumper argument.

Now I was wondering what you think about it?

Apistogramma might appear very different, depending on their mood and the environment they actually stay in,
so several decades of experiences have learned me that it's not only difficult, but often also quite unreliable, to compare fishes from a few photos.

However, as I've never observed 3 rows of spots forming abdominal stripes on my A. sp. "D10", don't see the same form of the caudal spot, never have seen the dorsal fin as serrated and extended on my A. sp. "D10" males as on the A. sp. "D50" males, I would, for now, consider them as two different species. Call me a splitter if you'd like
Of course I see a lot of features the two forms have in common, but according to my informations, they are collected very far away from each other.
It will for sure be interesting to see if the A. sp. "D50" is a mouthbrooding species like the A. sp. "D10"...

 

[Frank Hättich]

I'm quite sure that D50 isn't the same species as A. cf. helkeri (= A. sp. aff. Mitu). For example, males of D50 seem to get much more elongate dorsal and anal fins and they show pronounced vertical stripes or rows of dots in their caudal fin, which are missing in A. cf. helkeri. The large male in one of Tom's pictures seems to have a two tipped caudal fin, whereas that of A. cf. helkeri is always rounded. Moreover, the caudal spot of D50 males seems to be more irregularly shaped than that of A. cf. helkeri and their dorsal fin is colored differently.
Apart from this, at least one case of larvophilous mouthbrooding has been reported from D50, whereas this hasn't been observed in A. cf. helkeri so far (at least not to my best knowledge).
I think D50 is more similar to D10, but like Tom, I'm sure that these are different species too (Roland also agrees on this Jos, we named us "splitter" and "lumper" just for fun).

Thanks for the explanations guys

The only sure things in life are death, taxes and taxonomic revisions...

I've said it many times: Taxonomists change names to confuse aquarists!

That's similar to what I tell my buddy, a pathologist. On an annual basis, there aren't that many new diseases discovered. So, every five years they rename them all, so that we practitioners have to defer to them.
