Cardinal tetras?

Question

Are cardinal tetras ok in a small tank of there own? because i like them because of the red and blue on them.

Answer 1

If by small tank, you mean 10 gallons or less, then a school of 6 to 8 will do well on their own in a 10-gallon tank.

Answer 2

"Cardinals, being larger than Neons, really shouldn't be kept in a shoal in any smaller than 15-20 US gallons (55 litres plus) for a shoal of 6 or more, they should NOT be kept in smaller numbers.

A 25-30 gallon with 10-12 or so and nothing else but lots of lushous live plants and well aquascaped would look good."

Answer 3

Yes,you could also put some neon's with them,they look very smiler that would look very nice even with just the cardinals.Good Thinking.If you put a mirrorr for background it will look like you have twice as many.Yes i have used a mirro before just not with a Betta.
