This will be interesting to see.
The L144 that we know now is a simple colour variation of the common Bristlenose, not the separate species which is so rare that most people will never see on in their lives. Hence the breeding with the common.
The LDA072 may be a different story. It is an interesting question about crossing these. I am not sure how close they are, and if breeding them is possible. and further to this, if it is advisable. Given you are in England, I would be talking to some of the importers and seeing if you can import some more LDA072 and keep the species pure
Here in Aus we are not allowed to import any catfish :'( So what we have now is what we have got...since 1974! We get so jealous of people who can import!
