Hi All, I have a 8week old 40L fresh water tank and currently have it stocked with 12 smaller fish. Namely 3 endler guppies (M, M, F) 2 normal guppies (M, F) 5 neon tetras 1 albino cory 1 other cory Water quality has been ok, the last water check showed my nitrogen cycle is coming along nicely, with no ammonia, and pretty controlled nitrates /nitrates Filtering wise i have an integrated 800Lp/h overhead filter and also a smaller internal filter 200L p/h and a bubble air stone too. And I do 20% water changes every week. I'm getting mixed advice about whether or not my tank is overstocked so I thought I would come to the brains trust here. And If it is overstocked, what should I do? The fishes seem generally happy and doing ok for now if that helps.
