Question for the fish people: I'd like to house Pygmy Cory's in this tank alongside one friendly / curious betta.
I am using a marineland Magnum 350 cannister filter customized with a recirculation gate for a low flow rate into the tank. The filter is filled with fluval bio medium, and wrapped in floss.
I wouldn't like to have less than 7 Pygmy Cory's, for their mental health, but worry that 7 + betta in an 8gal would overstock the tank - even with the incredibly excessive filter / heavy planting.
What's the opinion on this?
