how many tetra can i put in a 14litre tank?
can i mix up different kind of tetra? (i want to stick to same sort of size, ie neon, cardinal, rummy nose, black stripe, glow light etc)
also, all but one of my old tetra died from neon tetra disease, but i have successfully treated the last one how long should i wait before giving him some friends - he doesn't seem too lonely and happily swims about in the open etc.
thank you!
