Hi folks.

New to the forum and have a question:

How does one tell the difference between a Hypostomus plecostomus and a Liposarcus pardalis? I've seen pictures of both, and it *seems* the lipo has a few ventral ridges; other then that I can't tell the difference.

The reason I ask is I have what I *thought* was a Hypostomus plecostomus, but after reading this post: http://forum.planetcatfish.com/viewtopic.php?t=808 (Hypostomus Plecostomus) and looking at the accompanying pics, I'm no longer sure.

Heres a pic; sorry for the quality, but he wasn't interested in posing and I had to squeeze the camera between the wall and the tank to get it LOL:

The easisest way to tell would be to count the number of dorsal-fin rays: <i>Hypostomus</i> has about 7-8 while <i>Liposarcus</i> has 13-14.
From the pic, I'd say your fish was a <i>Liposarcus</i>.

Jeez. The difference is that simple? I was all over the place looking for that specific bit of info! Some people look for love in all the wrong places; in my case apparently its not love - its fish info LOL

Course, he is completely uninterested in spreading that dorsal fin for me atm. Least I know what to look for now when he does; thanx!
