Okay, I've got my 6 gallon tank with 3 guppies, 1 male and 2 females... This tank is just a temp set up, I'm trying my own CO2 system to see how well my plants will grow, I haven't set this system up yet, I'll be adding an extra female guppy too, but I'm curious to know if the tank'll be fine with some cory catfish?
