Geophagus sveni "Paraná" temperature?

[GermanDude]

Hi!
What is the minimum temperature the fish can thrive?
Are 72 F too low?
What is your experience?
Thanks in advance!

72 is likely not too low. Much of the Parana River basin is not tropical but ranging from subtropical to temperate. Thus seasonally experiencing temps below 70s.

Thank you, but is there anybody here, who is keeping them at low temperatures?

As far as I know, those Geos come from Brazil, from an area where tropical climate is bordering suptropical climate.
Don't want to risk it to get health issues.
