I purchased a 1" Ancistrus temmincki from my lfs. My understanding of these is that the male grows a tentacle like patch of bristles on the snout and the female grows nothing or a very small row of bristles. Well mine is now about four years old, has grown to 5 inches, and has very long (longest are about 1/2 inch, most are 1/4 inch) and pointy bristles all over its snout. Is that female? I had heard they don't grow anything, but it definitely does not look like the photos of males I have seen. Maybe my lfs sold me another type of Ancistrus?
