ancistrus ID please

[kevin82]

Hi everyone, just after a hand ID'ing these 2 plecs I pics up from TVA in northumberland. They were sold as L059 but the fella also called them starlights as well and it doesn't tally up




Many thanks

Kevin

[kevin82]

I should note that since taking these pics a few weeks ago they have darkened down and the spots are more apparent. They are VERY busy eaters and not scared to be out in the open

Hi,

Milan

Can you explain based on which characteristics you identify this fish as

Ancistrus punctatus

'L182'?

The fish in the pictures clearly displays reddish/orange hue on it's fins which is not a characteristic of A.Puntactus.

Thanks.

[Loracidlover]

Sp. Rio Ucayali, not L182.

Identical to the ones I raised/bred.

Hi,

I borrowed a book Wels Atlas Band 2 by Ingo Seidel and Hans-Georg Evers and I read about Ancistrus sp. Rio Ucayali and Ancistrus sp. L120/L182 and I concluded that in my aquarium are swimming L182.

They wrote in this book:
The number of eggs in the Ancistrus sp. Rio Ucayali, .... 75 to 100 pcs
Number of eggs Ancistrus sp.L182 ............................300 pieces
Raising the Anc. sp Rio Ucayali............................. troublefree
Raising the L182..............................................difficult

Colour of fins is not decisive for me. My last spawning had 340 pcs. The colour of fry were very variable.
And fish in the photo looks just like mine. Maybe the fish in the photo is really even originally mine.: O))

Milan, What size are your A. punctatus? The Cat-eLog says they grow to about 250mm - which is twice the size of the Rio Ucayali species, which would explain the much greater number of eggs.

Looks like

Ancistrus sp`rio_ucayali`

to me. I had Ingo here for not so long ago, and he confirmed that my fish are

Ancistrus sp`rio_ucayali`

[Yann]

Hi!!

I also agree these are Ancistrus sp "Rio Ucayali"

Cheers
Yann

[claro]

"What size are your A. punctatus".... male have 16cm, but they are not fish caught in the wild, they would certainly have grown larger.
and I had by rearing fry exactly the same problems as described Ingo Seidel with rearing L182, maybe just a coincidence?

Hi,

Ancistrus sp. "L 182" and A. sp. "Rio Ucayali" are clearly discernible as juveniles:

Ancistrus sp. "L 182" has - at least up to 6-8cm - a reddish-orange margin to the caudal and dorsal fin and yellowish spots.
Ancistrus sp. "Rio Ucayali" on the other hand don´t have a clearly visible margin in dorsal and caudal fin (the caudal fin of some individuals might have one up to about 3cm TL), but only reddish-orange tips to the caudal fin. These tips tend to get lost upon maturation (just like in most other types of Ancistrus). Additionally, the spots - predominantly those in the fins - are reddish-orange at least up to 6-8cm (never raised any beyond that size), and only change to the typical yellowish-white color upon maturation.

So based on these easily visible characteristics, I would have to conclude that the fish of the OP is Ancistrus sp. "Rio Ucayali", in line with most of the others.
The other fish pictured here only shows one of the characteristics (dorsal and caudal is not clearly visible due to the perspective), but the red spots in the fins point toward A. sp. "Rio Ucayali".

I would suggest to be a little careful to identify fish by the size of their spawns or the ease of raising the fry. The first depends strongly on size and condition of the female (IME, fish constantly laying eggs tend to have smaller spawns than those only being stimulated occasionally). Note that I also had spawns larger than 200 viable fry of A. sp. "Rio Ucayali".
The second thing depends on the personal procedure to raise fry (NOTE: that does not make the one better than the other!). As an example: I find it easy to raise A. sp. "L 184". But that is only because I worked out my personal procedure that I now know works. That just does not make it work for others.

Cheers, Sandor

Hi,
i send more photos my fry to simplify

So, Milan, your fish appears to be L182. I'm still not convinced the fish in the original post are L182.

I'm still not convinced the fish in the original post are Ancistrus sp. Rio Ucayali,
because I think that the possibilities is more.

What a beautiful fishes!

[Jackster]

Here are a couple photos of the two species in question here.

This fish is wild, from Peru, and I have always considered this to be
Ancistrus sp. "Rio Ucayali". There is also a very similar fish from
Rio Nanay which grows larger to around 9" possibly 10" (25.4 cm).

I bought this species as Ancistrus L059 but I concluded that it should
better be named Ancistrus L120 "Red Seam" and I know that the parents
of this fish came from the Czech Republic so that seams to fit with the
same species Claro is showing. Personally I thought Ancistrus L182 was
a larger (8"-10") black fish with white spots? Maybe I'm wrong but I have
a photo of what I thought was L182 which will appear last.



Ancistrus L182?

[kevin82]

and more

Can I just clarify that my plec are identical to the plecs posted by claro with the red/orange seam on both dorsal and caudal fin, whatever they have been identified as.

Apologies but my original images are not clear enough I'll try o get more to clarify

[claro]

it is L 181

[kevin82]

it is L 181

sorry not this one, the one above it with the red seam on it's dorsal and caudal fin

Can you please confirm that the fish shown in Claro's post are L182's or not. My fish are identical to these plec with the red/tan seam on the dorsal and caudal fins.

[claro]

Hi

I would say that it can not be excluded that it is L182. Unfortunately it can not say for sure that it is L182.

[kevin82]

Hi everyone, I thought I'd post a few more updates pics. The 'fish' are now around 4 months old and very lively

[kevin82]

Hey guys

Just got 2 more of these and have found out that they are from the Czech republic

Not sure if this helps

[macvsog23]

What a beautiful fishes!

I totaly agree outstanding and as they are not shy a gem

[MatsP]

It indicates, in my mind, that they are the much more common (currently, at least) Rio Ucayali variant than the rarer Brazilian fish. However, being Czech captive bred (probably) specimens, who knows...

Hi,

I know exactly what is breeding in the Czech Republic.

1.Ancistrus leucostictus from Guyana (Probably Ancistrus sp Rio Ucayali) - These fish are breeding without any problems and their price is about 2 euro,have got white-gray dots , there are no problems with the floor, the main distinctive charakter are the eyes, Ancistrus leucostictus have got eyes very far from each other and are much bulging (Frog Eyes) .. here is a typical photo: http://nettakvariet.no/forum/showthread ... g-oppdrett
2.Ancistrus hoplogenys from Brazil......i bought my first fish under this name many years ago (presently it is L182 ) , these fish have a brownish-black color background,yelow- white dots, orange-white stripes on the ends of the fins, orange striped rays pectoral fin, breeding of fry is difficult and the price is around 4 euro

sorry to bring this one back up but here are some more images of the smallest of the 4 to try to help. 2 of them have lost the red seam along the fins and tail but still have the orange coloration on the fins
