geophagines

Hi everyone, I’m reaching out for help with a strange case involving one of my Geophagus sveni. For context, I recently moved across the state for college and brought my fish with me. My breeding colony of G. sveni was temporarily moved from their 180-gallon tank to a 75-gallon holding tank...

Hi Guys! Who here has taken care of this species? Are they really that aggressive? Will a single male work with say a group of proximus, tapajos and surinamensis? In a 360 gallon with a footprint of 8'x3'.
