Okay so i did that stocking calculator thing, but im not very sure how to read/understand it..
Along with that, i got this info from that setup (betta with 4 dwarf corys)
"You have plenty of aquarium filtration capacity.
Your aquarium filtration capacity for above selected species is 161%
Recommended water change schedule: 21%
Your aquarium stocking level is 116%"
Does this mean that i AM able to get 4 corys with my betta? or what?
