I have a 215L (57 US gal) planted freshwater tank and I think it might be overstocked. The ammonia and nitrite levels are both at zero, and the fish all have plenty of room to swim around, but still I just want to make sure its not overstocked.... I have...
14 x Neon tetras
6 x Glowlight tetras
3 x Long-fin spotted danios
6 x Rummynose tetras
4 x Harlequins
3 x Glass bloodfin tetras
2 x Baby platties
3 x Mollies
2x Congo tetras
4x Red fin tetras
3 x Golden algae eaters
2 (or 3, they are good at hiding) x kuhli loaches
1 x peppered corey
