So I want some color in my 20g which is why I am leaning towards cardinals (neons are fine as well, I hear you can mix the two in the shoal) but I like the black neons as well!
I am looking for a group of about 10 small tetras. My betta is pretty peaceful; in fact, he's narcissistic and prefers to watch his own reflection over chasing the frogs or shrimp. I already looked at the profiles from this site and wikipedia and someone's tetra blog so I know I can get away with these 2 types.
Do you have any preference? Why? any pictures?
I plan on picking them up this week at the LFS (not a chain store) so it will also depend on what they have on hand. I am also getting floating plants to help cover.
ETA- I have naturally colored gravel (see avatar), it is planted but I intend on planting more, it has 6500k bright LED light run about 6 hours a day, one side is shaded with silk plants, running a Marineland penguin 150 filter, change about 10-20% per week, Not sure on parameters or hardness (if needed I can toss an IAL in for lowering pH)
