L-190 and L-330 are from different parts of South America... L-190 is in Calabozo, Venezuela and L-330 is in Rio Gueja, Colombia.. two different rivers....
Although they might look similar.. they are two different species..
To be honest.... there has never been a report of successful breeding with Royal plecos... Also pleco breeding isnt exactly easy...... the issue with breeding plecos is the scale of it... To replicate breeding environment... you need sandy bottom and GIANT caves.. water jugs will probably be the best..
But you've got two different royals... it wont work..
Good luck with the sale..
