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.
Very active, though the tank is fairly low light towards the bottom as a lot of Echinodorus Ozelot leaves cover most the surface.
We had them what, I think about March time so I can try and find out next time we go where they came from but might be a bit sparse on the ground with that one. Was from a M/A store though, so might stand more of a chance with them.
I've owned a couple L182 that were already quite bristled at 3.5". One of them is now a male that's easily 7" TL. I'm not sure his bristles are much more impressive now than they were then, to be honest. He himself is stunning though.
The head shape looks a little long on these and the spots are already quite small for their size, so I'm not sure I'd call them L182, but I'm also not sure what else you should look to, either. Sorry I'm not more help!
Let me just point out that bristlenose ID is very difficult at the best of times. There are MANY different species that look similar, but originate from quite far apart. And the 100 or so Ancistrus species that are in the Cat-eLog probably cover less than half of all species that can be found in nature. Pretty much every decent size river in South America (except for Chile) has it's own species of Ancistrus - at least one species, that is. Or that's what Shane tells us, at least.
