I've heard some good things about Cory cats and bettas. I have a male betta fish and if
I get him a 10 gallon, how many corydoras could comfortably fit in the tank?
Would I need a filter? Because I don't think I'll get a filter. And if I don't have a filter, the tank wont "cycle" but the fish will be fine if put in "immediately" (when the water has settled, heater is ready, plants and/or decor is in....)?
I was thinking 4-6 Corys in a 10 gal, but I probably wont get him a 10 gal, this is just ideas being pitched around. If I did this how often would I need water changes?
