some folks like gravel ; and some like sand..sand can develop deadly gas pockets..i prefer gravel..
don't worry about sexing your pleco...it isn't big enough..wait until it gets to be 18-24 inches..it will be easier then..

cheers 4 the advice i jus really like the look of sand i might jus try a finer gravel
an i was wondering

i was lookin at getting another pleco but smaller
could i do that i have a 50gal tank and 1 8" pleco but ive been told if i added a smaller 1 my big 1 will kill it

Common plecos do get aggressive to eachother once they start to get bigger, I wouldn't put another one in a 50 gallon.
