I have wondered this for a while, as I like many different types of tetras, and will probably purchase 10 or more. If I were to say, mix 2 serpae tetra, with 3 neon tetra, with 5 cardinal tetra, would they school in separate groups with their own breeds, or will they swim all together?
Thanks for your time everyone, look forward to becoming a part of the community :)
I should think your research would indicate that the temp range for cardinal tetras and neon tetras is Quite different (or it should).
Although the cardinals and neons both appreciate soft water, the neons prefer much cooler temps than the cardinals.
Cardinal tetras I have kept enjoyed temps between 78 and 84 degrees F while the neons did poorly for me in temps much above 76 degrees F.
Serpae tetras would work with bleeding heart tetras,lemon tetras, Black phantom tetras,and possibly pristellas which are very quick and able to easily dodge the serpae's BUT.... you will need a tank large enough to house a group of six to eight of each species IMHO.
