nice fish caol, an lfs by me used to carry these bristlenose. they were getting them from a local breeder. if i ever see them again i am going to be sure to pic some up. have you found out if the smaller fish is male or female yet?

Hi!

The other two havent grown much...
This is one i hope could be a female...

Hi Chris!

With these new pictures, they really don't look like the common Ancistrus that you usually find here.
But with no origin it will be almost impossible to determine what species he might belong to while he is alive... the only possible chance would be to sacrifice several individuals once you ll get young from them and have them seen by some Ichtyologs that are specialized with Ancistrus...
So so far just call them Ancistrus sp
Cheers

OMG !!! this topic becomes more confusing every day. None of the pics posted in this thread are remotely like the "common BN" we have here in Australia.

Hiho!

In a nightshift photosession i "misused" the biggest of the three males...
got some big pics from that...
the bigger it grows the more i think it might be a hybrid of common bristle and L183...

the seams are still there but the fins are in bad shape as hes been picked on by the Haplochromis in a too small tank...:/

laast week i picked this little guy for 2 euros up...i wasnt sure if it resembled the whiteseams i bought in 2004
What do you guys think?

P.S.: Of the three bigger ones only the biggest has survived killing the others.

Looks like a Common Bristlenose to me. There are some with more white on the tail, and some with less. It appears to reduce as they grow older.

I forgot to add that its around 4 cm TL now

This is what the big male looks like right now:

Hi Chris!

the new one looks like a common as said MatsP!
Regarding your older male, it certainly has a strange dorsal and caudal fin...

cheers

check L279 on DATZ pic...it also has this strange pattern...different fish though...

That would be my guess.

Post by **Janne** » 11 Oct 2005, 19:47

I am thinking like kgroenhoej, it looks a little of both the common and A. dolichopterus.

Now, while I support the theory that the commonly available in the hobby Ancistrus is of dubious line, I think it's way too risky to say this one is a hybrid.

There are probably as many species of Ancistrus out there as Corydoras, surely there is room for this one. There are several L numbers close to this one and equally "just a bit different" from the next. Are we to call them all hybrids too? Or is it because this one is not in DATZ that we must assume it to be a hybrid?

Aside from that wishful thinking, why would Ancistrus from two different water types reproduce?

Sometimes a cigar is just a cigar. IMO.

PS It's not a million miles off L125.

Im still hoping to find a fitting female and see what the fry looks like.
In the shop i wasnt sure if the small new fish looked like this one when it was young.

Post by **Janne** » 12 Oct 2005, 12:08

I missunderstood a bit, I thought the big male was from the same "origin" as the other youngsters pictured and made a to fast deduction...sorry

I have not seen any species looking like this before and agree with Jools, there are so many different Ancistrus species both known and unknown and probably have we not seen more then a few of them.

I think it looks very much alike the ones from 2004. Did you buy it in same LFS (or near the same LFS)? If so, you should ask the LFS for the name/phonenumber of the breeder. At that size I don't believe they are imported (but the LFS should also be able to answer that). Sometimes the people at the local aquarium club also knows the name/names of possible breeder(s).

(that's a bit contradictrary, but I understand what you're saying

)
Other sp. can and do crossbreed. We've seen it with hypancistrus (even documented on this site) and with pond-breed Pterygoplichthys (the ones we all see (most of us anyway) at the LFS that doesn't look like anything we know) and probably also Hemiloricaria (L10a). I don't have prove that diff. Ancistrus sp. will crossbreed - but I find it very likely (especially if one of the two is the common Ancistrus).

Edit:

hehe - exactly my thoughts too. If the fish comes from a local breeder and if the fish looks like a crossbred - it might just be a "cigar"

Ancistrus sp(3) may be an amalgm of several whitewater species. However, what is being disucussed here is a blackwater / whitewater cross and that was what I was pointing out was less likely.

I think we are being too hasty to assume a cross without finding out where the fish came from. After checking with a couple of LFS this week, it appears wild caught Ancistrus are back on export lists and are being imported at around 1" in size.

Also, who's to say it's a hybrid and not a colour sport?

Almost every second week they import wild caught Ancistrus to Sweden and mostly as a "mix" but I have not seen this one yet...so here it's regular and I think the same in German too.

Caol_ila · Post by **Caol_ila** » 12 Oct 2005, 19:15

Its also not a fresh import as it came from a private breeder...so maybe its an older strain not commonly imported...

Yann · Post by **Yann** » 13 Oct 2005, 20:25

Hi!

I also bet that some of these "common" Ancistrus id could well be some wild caught as well.
There are several L# Ancistrus that have this coloration... and end up being called "common" because they look to similar to the one...but wihtout further information of its origin...

cheers

Hi!

The 2 Eurofish is from the same LFS as the 2004 fish.
This LFS told me they never order Ancistrus all they have are from private breeders.
Ill go there and ask for the breeder these days..

Post by **Janne** » 17 Oct 2005, 19:26

And this one...can it be your species?

I just pick these up with some other species of Ancistrus this weekend, they have just arrived from Manaus and are still in my quarantine tank.

Hi!

The small pickpup has turned out to be a common female.

I managed some nice pics of the UFO lately:

Dirty glas but you can see the spotted paired fins here.

White seam common bristlenose?
