Hi! I have a 16 gallon planted tank. The stocking is 3 Bronze Corydoras, 9 Neon Tetras, 8-11 adult guppies, and a ton of guppy fry. My plan is to buy a 10 gallon for the 9 neons with some cherry shrimp. I think that the Neons would be just fine in the new 10 gal or even maybe 12 gal. I don't really follow the inch per gallon rule. I look at if the fish are not stressed and if they are living a good life with enough space. So Idk but what do u guys think?
