Apparently I have no skill whatso ever at sexing plecos, so I've now decided I probably have 2 pleco males (whereas I used to hope I had a pair )
They are both commons & recently noticed they wree chasing each other a bit (the older & smaller on going after the younger . Now they are still both relatively small (older was was adopted) at about 7" a peice & they may just be cranky because my oscars (which they are housed with) are courting & have knocked down all the pleco's caves (I'm working on making some indesctrucatble ones ).
Will a 120 gallon be enough territorial space for 2 adult common plecos?
