Four tanks. 55g catfish community, 14g Aspidoras breeding project/office tank, 20g Corydoras + kuhlis, and a 75g that primarily houses an unfortunate Acanthicus adonis, the largest of all loricariids, that was sold to me as the far more manageable Pseudacanthicus L097. It is still relatively small, but might not stay so for long...
I ended up liking the Acanthicus more than I expected, and can actually get a 250g stock tank for it at an affordable price, but then I'd run into the unique problem of having to explain myself to the downstairs neighbors about why a plastic tub containing a literal tonne of water crashed through their ceiling. Apartment buildings over here aren't really designed with monster tanks in mind.
