No problem man, I'll move it to the appropriate section for you.

As for the differences here's 2 links to Planetcatfish that explain the differences, just check the descriptions

Wich one do you think would be the best in a 140 gal discus tank?

Thanks for the links..!

I acually though the l191 was smallest but now i know better!!

Thanks man

Besides the size difference(which I would take with a grain of salt as PC won't change a maximum size unless it's extremely well documented) they look very different as adults.

As juveniles 191 has "a windowed or clear caudal fin and white tips to the fins" as well as the dull eyes that they get their name from. As adults they lose their intricate pattern and become gray with longitudal stripes. Check the image of the adult and you'll see what I mean.

As an adult 190's pattern gets more intricate and in my opinion is the more attractive of the two. Again just check the adult pics of both and you'll see how different they become.

I'd also be hesitant about adding them to a discus tank due to their high waste output and the discus need for good water quality. That plus some pleco's have been known to suck on fish and a discus is a slow moving target. If you do try though make sure you've got wood for the panaques as it's intergral to their survival and is an often overlooked thing that isn't mentioned to novices who wish to keep them.

+1 with the last paragraph. Nobody "needs" a pleco, if you want some interesting bottom dwellers to keep with your discus then there are certainly many potential species out there, but don't think you're getting some magic cleaner fish that eats poop and craps out clean water...

IMO Hypancistrus Spp. would be a better option for a discus tank, they'll do far better cleaning up the let over high protein food from the discus, and don't get anywhere near as big (or messy) as a Panaque.

Agreed. If you are feeding high protein food, your Royals could develop bloat. Even some Hypans, which are carnivorous plecos, can have problems in discus tanks. L134 are great for discus tanks as they are small, striking (black and white) and like the warmer temps (above 80s F). However, if you feed a lot of beef heart to your discus, L134s can die of bloat. For more info, on planetcatfish, look up "discus apistomaster l134".

Thank you very much. I will make sure that i have alot of drift and bogwood.
I have in 7 years kept malawi and tanganyika cichlids, so i wouldnt call my self new with fish, tho im new with all these South Amercian species, and its great to be able to get help from you guys. Id also just ask what you think is the normal adult size for both species, and at what age they will be when they are that size. Thanks again man.

I wasnt thinking that i was getting some sort of a magic cleaning master fish, i just wanted a fish that could eat the food the fell past the discus down to the bottom of the tank

I'll take a look at the Hypancistrust I also though about putting my little group of S.Eupterus down there.. But theyr supposed to be a little agressive, even tho i have never seen any agression from them to any of my other fish, whats you guys input on that?
