[Bas Pels]

I think it was 5 years ago that the genus Acantopsis grew a lot.

Earlier, it was all A choirhorhynchius, but than this species was split into 8 or so. All closely related, soome growin a few cm larger than others, but the care is generally the same:

clean flowing water, sand and food tendiing to be more animal than plants. temp? No heater required, around 20 C would suffice
