I understand what Paulo mean: this is in fact 3 different fish and not 6 pics of the same individual...

They were in his tanks and suddenly some started to change the colortation:
The photos are of 4 different fishes.
Photo 1 and 2 are of the same fish, 3 and 4 are of another, 5 is of another, 6 ...

OKâ?¦
But in the same tank, with the same conditions, there are individuals with normal color, and others with the changing colorâ?¦
I will try to put a photo of all individuals hereâ?¦

I think thatâ??s you that donâ??t understandâ?¦ That kind of answers donâ??t satisfy meâ?¦ My scientific exigency needs moreâ?¦
I work with this kind of fishes for some years and it is the first time this appendâ?¦

Well...
To see if I become to understand...
The problem is this:
- The photos are of 4 different fishes;
- When we receive the fishes, all they had this aspect: http://loricarideos.no.sapo.pt/Aquariofilia/L75.jpg
- At some time, some of them had started to change of aspect;
- The fish of the two ...

I know what the problem might be!!! It might be stress related as the pictures are taken OUT OF THE WATER. How would you like it if i took you under water and photographed you. I MEAN HOW CRUEL IS THAT? AND I'M GONNA REPORT YOU TO THE R.S.P.C.FISH
Sincerely your answer donâ??t deserve any commentâ ...

But the problem is that they already had the normal pattern/color and lost thenâ?¦
They have around of 9-10cm

P. leopardus came from Guyana
and
L-114 came from Rio Negro in Brasil...

Dear Friends,
I already see some strange phenomenon, but this surprised me for completeâ?¦
I know that there are some species of Loricariidae that although to be born with the perfect colors, they become albinos, butâ?¦ I never knew that phenomenon occur with L-75 Ancistomus sp. as it is registered ...

Walter wrote:I know crossbreeding between ... Hypancistrus zebra L-46 and Hypancistrus sp. L-98, the fishe grew up and did not die.

L-46 and L-98 is the same specie Hypancistrus zebra. L-98 and L-173 are variants of Hypancistrus zebra. Soâ?¦ This cross is normal.

I prefer the Panaque nigrolineatus of the Xingu river in Brasil (or from Araguaia, in Brasil too). They are very beautiful, I think more than the venezuelan ones.
Sincerely,

Yes... It can be a variation in the somatic characteristics of the specimen.
But... It's strange, because this charateristic (high-fin) no one see it in the past in this specim. By that reason I said that it is a mutation.
Paulo.

I knew the exporter and I ask him if he export that kind of fish to Glaser.
He confirme to me that this apend (and it is the only one he see in 6 years).
So, this is a mutation.
Paulo

I think that the solution for that one that donâ??t beleve this is a true photo, is to bay the fish to the Glaser (and pay the price he wount).
Sinserely

The photo is not a fraude.
I knew the exporter (the Glaser suplayer) of this fish, and, I ask him about that fish and he confirme to me that he export that fish to Glaser. This is the only one that he see in 6 years of exporter. Naturaly is a mutation.

Tanks Dinyar... :-)
Barbie, the tank has an excellent filter with plenty of Siporax (Sera) the water change is made very slowly and constantly with the same kind of water at the same temperature. This is the reason of 0 nitrates, nitrites and ammonia. The tank has an excellent oxygenation.
Sincerely ...

The Sera Nitrivec is very good. I use that with success. If you get some filter material from someone you probably can carry some diseases too.
Sincerely,
Paulo

My water is naturally soft.
Like I just said the fishes come to me directly from Peru.
Thanks.
Sincerely,
Paulo

The problem is that here in my country there is no one capable of give me the help I need. They have no acknowledgement in this area. This type of hobby is very recent in a massive way.
Yes, the fishes come directly to me from Peru through an importer friend (from the airport to me).
No, their ...

Dear friends
I recently buy 100 Otocinclus affinis that come from Brasil. But they are dying at a rate of 2 to 3 a day. I donâ??t see any signal of disease and the water are soft and clean (pH 6-6,5 and very soft) like in the origin river and a temperature of 26ºC. They are alone in a 200 liters ...

They are in my tank from Saturday. Some are dead at arrival and others are dying at a rate that I said above until now. They are alone in a 200 liters tank with new water. Around 0 nitrates, 0 nitrites and 0 ammonia, with constant water changes. There are no signals in the fishes of any diseaseâ ...

Dear friends
I recently buy 60 Corydoras arcuatus that come from Peru. But they are dying at a rate of 4 to 5 a day. I donâ??t see any signal of disease and the water are soft and clean (pH 6-6,5 and very soft) like in the origin river and a temperature of 26ºC.
I would like to have same help ...

Like I said, I don't have any substantial problem with other generous of Loricariidae (like: Hypancistrus, Panaqolus, Pseudacanthicus, Ancistrus, Hypostomus, Peckoltia, Scobinancistrus, Panaque, Ancistomus, etc.).
I made exactly the same quarantine to Baryancistrus (L-18, L-81, L-177, LDA-33), that ...

It's not 100litros but 150litros

Hi
I put 30 fishes in 100litros tank with daily water changes.
Walter the Baryancistrus that survive to the quarantine never became a problem any more. My problem with this fishes is exclusively in the quarantine time, but normally the shippers in the origin countries export them practically when ...

Dear friends,
I sincerely think that my problem with Baryancistrus is that I need a different quarantine of the other my imported Loricariidae (Hypancistrus, Panaqolus, Pseudacanthicus, Ancistrus, Hypostomus, Peckoltia, Scobinancistrus, Panaque, Ancistomus, etc.) in spite of all was of the same ...

The problem is that when I import Baryancistrus (L-18, L-81, L-177, LDA-33) I import the other Loricariidae (Hypancistrus, Panaqolus, Pseudacanthicus, Ancistrus, Hypostomus, Peckoltia, Scobinancistrus, Panaque, Ancistomus, etc.) from the same origin too, and the last ones donâ??t give to me much or ...

I would like to know if the Baryancistrus (L-18, L-81, L-177, LDA-33) are the more fragile Loricariidae. This is the loricariidae that gives to me more problems to quarantine, and died a lot.
I import other Loricariidae (Hypancistrus, Panaqolus, Pseudacanthicus, Ancistrus, Hypostomus, Peckoltia ...
