Acryllic safe pecos?

  • We are currently upgrading MFK. thanks! -neo
If it was my acrilic tank I wouldn't do any plecos.
 
Some of the "Whiptail" varieties will do ok. I had a 20 gallon acrylic tank, that used to have a whiptail that did no damage to the tank. The royal on the other side however did not leave the tank looking so hot. That was a long time ago, and a big mistake.
