Hi

and Son. I have had a Leichardti since it was approximately 4". Over three years later, it is now ~21-22". Since the beginning it has been in the same tank with a blue phantom pleco (4.5") and gold nugget (3"). The plecos were there prior to the Lei, but I truly don't think that makes a difference who came first in my case. The plecos are very slow growing, and the good news is the Lei leaves them alone and has never ever bothered them. In fact the Lei chases the two red spotted Severums that are also in the tank.
I've had two Lei's, and both have had protruding lower jaws (as

mentioned) Not the best looking, but it's mine ; - )
