the gold one is 6" long in a big tank, and has been that length for several years.
the other one is 8" long and also has stayed that length in a big tank. I just wanted you experts to positively ID them for me. thank you very much.

Hey Reva

The fish in your top photograph is what we in the U.K. know as the Golden Albino Plec. There is much debate over the correct scientific name of this fish so you will find it listed as the golden/pond raised version of Liposarcus/Pterygoplichthys pardalis.

The fish in photographs 2 and 3 is Pterygoplichthys gibbiceps.

thank you David. I bought the little one as a "Golden Albino Plec" (same name here in the LFS's), but he hasnt grown big enough to be a gibb, and his eyes are not pink. (the pink in the photo is reflection of the flash).
I believe the bigger one is not a gibb either, as he has a much bigger dorsal fin and different color than the gibbs I see in the big display tanks , and he also has stopped growing at his size for several years. Why do you not think he may be a Pterygoplichthys joselimaianus? I was hoping for a confirmation that that is what he is. I have no idea what the golden one is, but will read up on your Liposarcus/Pterygoplichthys pardali and see if he matches those. thank you for replying to my post.

Hey Reva

I think it is true to say that Liposarcus/Pterygoplichthys pardalis is 'the slowest growing Plecostomus known to man'.

It takes them years to obtain their full size of 60cm.

Their eyes are not always those of a true albino.

The photograph below was taken, by Sue Marshall, of a fully grown Albino Golden Plec., which we were told was 15 years old.

Hey Reva

David Again

Did the dark coloured fish in your photographs look like the one below when young?

Sorry for the poor quality of the photograph but this is P. joselimaianus - L001. If we have a 'match' then I was wrong above.

It is just that the fin margins of P. joselimaianus are not usually as thickly set as those of the fish in your photographs.

Wow @ the old golden plec!!! /ohmy.gif" style="vertical-align:middle" emoid=":o" border="0" alt="ohmy.gif" /> they seem almost prehistoric looking sometimes.
Yes my dark one looked exactly like your photo above. I was looking through the pics on this page and trying to place him, and if you look at gibbs, his caudal fin is round. look jose, and he matches again....
