stocking options neon/cardinal/zebra danio 10g

im restocking my aquarium and cant decide on which fish to add. iv got a 10g tank and 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

I've got Cardinals & Bloodfin Tetras and Zebra Danios in my tank (6 of each) and they all get along just fine. The Bloodfins and Zebras intermingle but the Cardinals stay to their own. My tank's bigger than 10 gallons though so I don't know about any possible overstocking issue you might have.

The neons, cardinals and zebra danios will be peaceful together, but their water requirements are a bit different. Maintaining fish in an aquarium that have the same basic requirements will enable you to provide the best environment for healthy fish.

The main difference here is temperature. Zebra danios occur in faster flowing streams and prefer cooler water, around 64-74F (18-24C). This also suits the neon tetra. Cardinals on the other hand prefer slightly warmer temperatures, 78-79 is ideal, and they can tolerate low 80's (neons and zebras would not do well at this high a temperature). Neons and zebras also adapt to different water parameters better than cardinals. The latter are soft, acidic water fish, and while many aquarists are able to adapt them to less favourable water conditions, their overall health is better in soft and slightly acidic water. They can live for more than 10 years in the corrct water, but seldom reach anywhere near this age when maintained in harder, alkaline water.

All three species are shoaling fish, meaning they live in groups and will be more comfortable and thus healthier if maintained that way in an aquarium; a group of six of any of these species would be good, or more if space permits. A 10g is limited space, but a group of 6 neons and 6 zebras would be OK if you do a regular weekly partial water change and don't overfeed. Alternatively, a group of 9 or so cardinals in a 10g with live plants would be a stunning site.

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]
