stocking options neon/cardinal/zebra danio 10g

im restocking my aquarium and cant decide on which fish to add. im stuck between neon tetra,cardinal tetra, and zebra danio. i was thinking maybe 6 of each tetra and then maybe 3 or 4 zebra danio but im not sure if i could stock more than that or maybe i cant have that many. i was also wondering if the different tetras might school together.

its a half a inch of water and you think your gunna drown

No you cant have that many, but what you can do is have 15 neon tetras, but you cant get all the tetras at once you have to get the fish in intervals. Neon Tetras are the smallest and have a very small bio-load therefore letting you have more fish

Personally I would rather go with Cardinal tetra's, I think 10 (possibly a few more) would be ok. The advantage with cardinals over neon's is that they don't (If I have read/heard correctly) get neon tetra disease.
Also I have found that it is better to have a larger school of tetra's rather then put a few in with some others as they seem less stressed. As for the zebra danio's I'm not sure, I have heard they like room to swim but I might be mixing them up with another type of fish.

All three species mentioned are shoaling fish which means they must be kept in a group if you want healthy, stress-free fish that will exhibit natural behaviours. In a 10g, that pretty much means one species only. Seven or so of one of these would be fine, although I wuld not go with zebra danios because of the activity level someone mentioned already; thy are more active swimmers than cardinals or neons and would do better in more space. Cardinals prefer slightly warmer temperatures than neons. Both should have plants to replicate their natural habitats. A shoal of 7-9 cardinals or neons in a planted 10g would be a beautiful site. Six or seven would allow room for a small group of one of the dwarf corydoras species (Corydoras pygmaeus, c. habrosus or C. hastatus) to complete the setup. Provided of course you are regular with tank maintainance (weekly partial water change of 30-40%), and plants significantly aid in filtration. More filtration is carried out by healthy plants than any mechanical filter.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
