then, the females lack odontes at hard fin?

and other question. This fish weighs 10cm, and he looks like L168 than to L052. it's incorrect Id as L052?

I have understood than the sexual differences in Dekeyseria sp. L052 based in a bigger odontal interopercular and same in the pectoral hard fin, but ...
do the females lack almost completely of them?
The females can possess a greater growth odontal in the end of the hard fin although the remainder ...

Any idea? :?:

To me, it's very similar to Ancistrus sp. (1) at Cat-elog, but caudal coloration isn't equal.

Maybe a young fish of:

- http://www.planetcatfish.com ...

The first I doubt it's a L066 (I think), but it's very similar. Maybe L174.

The second, probably it's a L316, but when I take this photo the fish wasn't good health.

Do you know the origin?

No, I don't know.

After comparing with another photos, I also think is a Panaque changae L226.

These photos are of juvenile fish, I'll try to take more of another adult fish.

Thanks.

second (little stressed):



Both sold with another two L287, but the upper hard ray of the caudal hasn't equal the lower, any idea?

Thanks in advance.

sold as Ancistrus sp. "Maranhao", this is correct?

It's very similar to F.vittata, but isn't. And looks like F. gracilis, but the caudal coloration isn't the same. Any idea?

Thanks in advance.

Thanks Jane.

Then, L129 and L316 only are different in the size of the eye.

At first I think this fish are an L066, but after I read this post:
http://www.planetcatfish ...

I think is a Hypancistrus sp. L129, isn'it?

Finally, I think it's correctly as L316.

Another detailed photo of the mouth.
