My blue panaques (L239)

Not coloring up fully yet, but eating well. I've only had them about a week or so.

Nice! Have they started munching on wood yet?

Very nice fish, great blue coloration already!

It's unlikely that they will: despite their common name, these fish are no true Panaque's, and neither are they wood-eaters. Given the shape of their mouth, I think they're Aufwuchs-eaters (like Baryancistrus): maybe they graze on wood and will ingest soft wood particles while doing so, but they are no wood-eaters in the true sense of the word...

I have one they are just as pretty as mine is.

Does anybody know how many species have been placed in "Panaque" and aren't true wood eaters?

Besides L239, I haven't seen Loricarids in aquarium stores being sold under the name Panaque.
Sometimes, Hypostomus species previous known as Cochliodon are also called Panaque: it's incorrect, but at least those fish are wood-eaters.
And some ichtyologists (whether rightfully or not I don't know) have placed Scobinancistrus species within the genus Panaque, those fish aren't wood-eaters (they're primarily carnivorous).

Scobinancistrus is tentatively placed under the Panaque label by Jon Armbruster, based on the fact that they have very similar features. Ichtyologists don't usually take feeding habits as part of the species definition. Rather, they rely on physical features such as counts of scales/scutes/plates, teeth, proportions of different body features (e.g. body-length in relation to head-length, eye-size in relation to head-length, etc). Using those type of metrics (apparently) Scobinancistrus isn't noticably different from Panaque.

Certain lasiancistrus also feed on wood.

I apologize for hijaking your post, Rich, but I'm curious.

Since dentition is taken into consideration with identification, I wonder if this is an indirect way of looking at how a species eats, but not what. Am I way off?

I dunno if you are way off or not. But, mine do not eat the wood I have in there with them. poor things are getting over a case of ich. I ended up having to medicate, as the salt treatment I tried didn't seem to work. I used quickcure, and heat. The cysts are dissapearing slowly, but they are much more active and eating again.

Anytime I encounter ich, I wonder what caused it (it is indicative of something else usually). I'll be keeping a close watch. I have not noticed any poop even though they are eating, so it makes me think worms, but I don't like to just jump right to medication if I can help it.

I do have some prazi powder around just in case.

Yes, to some extent. The number and shape of teeth obviously develop depending on feeding hapits, which in turn is somewhat affected by WHAT the species eats as well as how it gets to it's food.
