I agree, they should have different L#s.no plecos are fine in a sand substrate, i've just always used gravel from a maintanence point of veiw. just dont buy if it has a sunken stomach. any other things would be obvious that it is unhealthy. do you know if it Hemiancistrus subviridis or Baryancistrus demantoides? i dont know why these two havent had a seperate L number
