Ok I was asked several years back on this forum or another forum what was my big interest in the Glyptoperichthys family of the pleco world. Now known as Pterygoplichthys they are still my favorite family of the loricariidae. One I always wanted was Pterygoplichthys scrophus but have always been hard to find. I think since there not colorful like some other pleco's there not desired and for that reason are not farmed and not really imported.
Luckily I was able to obtain 2 of them which were wild caught. There are two pics that I saw that made me absolutely love and want a Rhino Pleco. They are here at this site

This family has several other pleco's I like. My favorite being the gibbiceps and then joselimaianus followed by scrophus then pardalis. There are others I like but are way harder to obtain. The size (I dont mean length but girth) of them and the broad heads but gentle nature (except to there own kind) has drawn me to them. They just appeal to me.
I remember my mom use to feel sorry for "algea eaters" as there refered to out here. She always felt bad though cuz these pleco's were always kept with mean cichlids and had fins torn and missing in some cases. I think thats were my interest in them was sparked. That was about 20yrs ago.
I have since then done lots of reading on this family and now find it rather easy to identify any member of this family were it seems others still struggle a bit. I know they arent colorful and require big tanks but this has been and propably always will be my favorite family of the loricariidae's.
Just a lil peak inside my mind and how I feel bout pleco's.
