I keep and breed several of the B&W Hypans: zebras since 2oo6, L173b since 2009 (all sold/let go this year), L236 two groups: 1 from the Budrovcan line since 2012 and 1 Tank Raised group since 2016 , L450 since 2012 (all sold/let go this year), L173 two groups: 1 wild caught fish since Oct. 2015 and 1 Tank Raised group since Dec 2015. I kept and bred the contradens for several years and they too have all gone to new owwners.
173 are one of the slowest growing Hypans with which I have worked. I had a great conversation with Eric Bodrock of Alloddball about this at the NEC in 2018. He was complaining about how slow they grow. My reply was as sarcastic. "Tell me about it." I also use a lot of Repashy (S&G, BS and SG) and frozen foods for all my plecos and corys. My big clown loaches absolutely shred Igapo Explorer (fornerly Fruut Luups).
I do not consider any of the Hypans above appropriate for a pH of 6 let alone lower. I think you are likely to kill them in under 6. I was willing to try the contradens because they are listed as coming from rivers which have sections of very acid, stained waters. But they are not acid from end to end. Plus contradens are a spotted Hypan.
Not many fish will work in acid water. You almost have to get them as imports for that. If you watched the first of the two vids I posted it should give you some ideas about what cohabits with Altums- flag cicglids, eartheaters, neon tetras (I have rummynose with mine). They did show one pleco, but nothing like a B&W Hypan.
