Did you know fantastic help is an anagram of Planet Catfish? This forum is for those of you with pictures of your catfish who are looking for help identifying them. There are many here to help and a firm ID is the first step towards keeping your catfish in the best conditions.
Can anyone help me figure out what kind of Royal Panaque I inherited? He was part of a very large tank at my Dr.'s office that I have always admired. When the tank got badly cracked, they called asking if I was still interested. I've ordered a 120 gallon tank for a more permanent home for him (or her?) that should arrive this week... Until then, any chance someone can tell me which type of Royal he is?
I apologize for the imperfect pictures -- trying to get close-up shots of important bits, but he's a bit shy & the camera doesn't always cooperate
Thanks in Advance! Amanda

There are many undescribed species traditionally confused with P. nigrolineatus (especially those who have not yet trained their eyes). By far the most common one, IME, is L191, and is usually the form you see instead of P. nigrolineatus. L330 is another form that is similar to P. nigrolineatus and possibly the same species as P. nigrolineatus. There are also the Brazilian Royal Panaque such as Panaque armbrusteri and the other Brazilian species of Royal Panaque; in the past on PlanetCatfish, all of these Brazilian forms were termed "Panaque cf. nigrolineatus", although more recently they were all changed to "Panaque cf. armbrusteri".
I can't really comment on sexing by genital papilla, that's not something I usually rely on. I'll let someone else answer that.

thank you ALL for your help -- I really appreciate it!
I didn't realize it was too small to be sexed yet... just hate calling it "IT!"
Rob, I can try to get a good picture of his belly, but I looked at the photos in the CatElog of L330 & all these guys look entirely spotted, not striped. My guy is definitely striped (at least for the most part). Would a L330 have stripes as well? Rob, you want a picture of his underside (belly) -- any specific area? He/she isn't always so obliging about posing, but I'll try!
Again, thanks for everyone's help! And trust me, I'm absolutely keeping him or her, regardless! The new tank should be here end of the week... and I will have LOTS of questions as to how to best set it up so it's perfect for this monster
