My guppy tank is about 10 fish umder max capacity, and right now it has around 20 fish. If overstocking starts to come up, I'll put a 55/75 gallom filter on it. I already do weekly 40%-60% water changes. One thing that really bugs me about aqueon bowfronts is that water evaporates so fast. My light is on the average amount of time a day.
Thats how much water loss after changing the water 2 days ago. Plus my cobra gup came to say hi lol.
lol bristle nose also
