As I said I am a complete beginner and was not given this information when I bought them, maybe now get a few more.so hard water and high ph is ok for mollies/platies, but neons and black fins are soft water fish that like more neutral to acidic waters if memory serves me correct... Also, one other thing to point out, since those tetras are schooling/shoaling fish, they should be kept in groups of more than 5
