I'm planning to house a small school of Red Phantom Tetras in my 20-gal community tank, and I want to make sure they thrive.
It is my understanding that - in general - Tetras prefer soft, somewhat acidic water... at least that's their natural habitat.
In Philadelphia, we have moderately hard water on the alkaline side. My tap and tank water have a very stable pH of 7.3/7.4. And the reservoir from which my tap water originates reports GH of 9.5deg and KH of 4deg.
Considering these parameters, my LFS suggested that Red Phantom Tetras would do better than some others (e.g. better than Neons).
Does this advice sound plausible?
Any thoughts on helping them thrive?
(I don't want to mess with my pH chemically)
