Here's an extract from the authoritative article 'Chaos in Black & White' that appeared in Reef to Rainforest regarding L173 and 173b ....


"Hypancistrus sp. L173 is a highly sought-after but controversial form from near Belo Monte. The similarity to H. zebra is striking, especially in juveniles. However, there are differences: L173 has brown eyes, a rather off-white base color, a variable wormline pattern, a taller and more compact body, and a longer caudal fin. This form also grows larger than H. zebra. In the hobby, L173 was unfortunately hybridized with H. zebra to produce more of the “L173 type.” Some L173 lines differ so much from the norm that it is hard to believe that they belong to this form. Not all individuals have the typical pattern. Some offspring of L400 show a pattern similar to L173, hence, a close genetic relationship is very likely. It is important to note that L173 is not a morph of H. zebra, as was previously assumed.

The commercially available L173b should be regarded with skepticism. (The “b” was introduced by Aquarium Glaser. Specimens that differ externally from the normal habitus were identified with the letter “b.” Individuals with a typical pattern and color would therefore be “L173a.”)"

TY- I reference that article when I sell 236. I know that the fish I have are real 173. They are different from the 173b which I also have. I have my own theory about the 173 which may or may not be correct. Unfortunately, it is based only the ten 173 I have which have spawned and another unrelated group of 14 F1 purchased via the same source but not bred by the seller. Then there are the fry I have gotten from the first group, which very well may be wild fish. But there is no way to know this for sure. However, I believe it to be true.

I can also tell you that experts I greatly respect were kind enough to look at some of my F1 group and they confirmed they are what I bought them as. I needed to know for sure before I could say any fry they grow up to produce are the real deal. I never want to sell a rare fish that is not really what it is supposed to be.

A good friend recently cam by to take photos and vids of some of my fish and to take some home to sell. So I should have pics and vids of all of the fish were are discussing to include L450, L236, L173b and L173. I have copies of what was shot day one but she has to send me the day 2 stuff. She also shoots raws and high quality jpgs, so I need to crop and resize stuff to post it here. But I will do so in the not too distant future. I have no clue re editing vids.

TwoTankAmin - It would be great to see pics of L173 and L173b side by side so that we can understand the difference between the two. Look forward to seeing the pics.

How much does L173 fry go for in the US?

I don't know of anybody selling them. That means there are so few people spawning them that it is hard to find anybody doing so. It isn't that they are super hard to spawn, they are a Hypan after all. But finding them in the first place is the problem.

If I put all 10 of my breeders in front of you, it would be easy to see they are likely the same species from how they look. The 173b are supposed to be offspring that do not look like 173. I am not sure any more if this is the case. I sold 6 adults out of my grow tank today. I had gotten a spawn or two in the tank which means somebody is good to go. None of them looked like 173. Some were really nice looking fish, but they would never be identified as 173 based on their appearance.

My F1 group I purchased is now in the "zebra phase." One or two have started to show a hint of the zig zag pattern. I have pics, but I have to shrink them or Jools will sue me for commandeering his server to host my pics :p But here are two of the 173 breeders I did get resized (the pics not the fish).

Edit:
I just remembered, in the very first post in this thread, I put a link to extensive pictures of the L173b I got from Glaser. http://twotankamin.smugmug.com/Fish/L-173b/n-chr5b Compare them to the two above :)
Edit: to put Rachel's credit on the pics.

Here I am years later and It is time for this species to depart my tanks. They will be going to new homes shortly. I recently did a head count of offspring I still have for the recipient. I thought they would bring this thread to its conclusion by posting the pics. Unfortunately I breed much nicer fish than I take pics, sorry.
