Good fishes for a heated 20 gallon standard, My PH tap is 6.8.
I'm thinking of using a sand/live plant growing substrate, Something I've NEVER done before, and using driftwood and growing live plants along with fish. I already have a glass lid( going to buy the lighting sep for plants as I've heard the ones that come with kits are inferior for most plants,) the filters a penguin 150 BIO-wheel power filter. This will be a heated aquarium, 78 to 80, What's a good heater to buy?
My taps PH is 6.8, so what types of fish are good for me to try out?
