Thanks Lloyd. yea... I always loved cardinal tetra. They just look so beautiful when they flash their blue and red. Such striking colours. To see their true potential you have to have them in a black water tank. The store I bought them at (Finatics) has them in a dark tank and man...they shimmer so beautifully.

Anyways, I am happy on how colourful they look in my tank. I hear from the FS employees that I really spoil my fish. They love daphnia...and basically ignore the regular flake/pellet foods. These cardinals are also super lazy. ...lol. They don’t bother eating stuff that floats on the top..they want stuff to pass by them across the current and then they eat it. Such spoilt brats. Lol

What's the pH of your Tetra tanks? I remember that Tetra's need a really low pH to breed.

The pH is 6 - 7.

I think as long as they have acclaimatized to our water, they are fine. I don’t know if these are tank-bred, but their behaviour is akin to wild-caught fish. (Full disclosure: maybe their skittishness is actually due to me being nosy and in their tank all the time doing maintenance and I do not have much experience with aquariums to confidently comment on wild behaviour vs tank-raised behaviour )

In mississauga, our tap water has a pH of ~ 8. ADA aquasoil is known to increase acidity thereby dropping the pH. Hence, at the time of each water change, pH changes from 7.5 to 6 or high 5 as the week goes on. I do water changes once a week / twice on occasion if I have time.

Cardinals are not that easy to breed if I recall correctly. They need a more subdued black water setup??
