PH of tropical fish tank

Optimum Freshwater pH

The one bit of aquarium chemistry that almost everyone has some familiarity with is pH, which basically is the measurement of how acid or base a given solution is. As most will recall, a pH value of 7.0 is neutral, while higher values indicate alkalinity and lower values acidity. In nature, tropical fish might come from waters with quite low pH values (e.g. Discus and Tetras from the Amazon River Basin might be collected at a pH of 5.0) or very high values (some African Cichlids might be found at pH 9).

Since pH is a familiar concept and is easily tested, many beginning hobbyists overemphasize its importance and go to great lengths trying to achieve some "Optimum pH Level", most often aiming for the neutral value of 7.0. This is quite often unnecessary, and can cause problems.

Generally speaking, the optimum pH for a freshwater community tank is whatever the pH of the supply water is. Water with a pH value between 6.5 and 8.0 is acceptable to keep and even breed most common tropical fish. And in the cases of the few fish that require lower (Discus) or higher (certain unusual African Cichlids) pH levels, other factors such as Water Hardness and Total Dissolved Solids appear to be much more influential than the pH itself.

Sudden changes in pH, on the other hand, can be very stressful to fishes - even if the values remain in the recommended range. Since many local fish stores make the fish adjust to the local pH, the aquarist who artificially adjusts his pH may actually be causing undue stress, rather than relieving it. In addition, tap water is sometimes heavily "buffered", meaning it contains chemicals that resist pH change by "absorbing", in a manner of speaking, acids and bases. The addition of a pH adjusting chemical will change the pH for a few hours or days, but it snaps right back, frustrating the aquarist and stressing the fish.

Ok, basically, no, you can't put zebras and goldfish together. First of all, your tank is probably way too small for even one zebra. Secondly, they have different water condition requirements. I can't think of zebras' preferred pH and dH off the top of my head, but regardless, temperature is the biggy. Zebras are tropical

As long as the water in the tank has been dechlorinated, temp and pH are within reason then I don't see a problem.
You have 10 gallons of water and only 1 neon fish. The bioload will be small and your fish will be better off in a 10g tank then in a jar with a tiny amount of water. Also, it's very stressful for the fish to experience 100% daily water changes. You can leave the fish in the 10g and do 50% daily water changes. Just make sure the temp and pH match.
Get a heater asap. That water is too cold. Neons are tropical and require temps in the 70s. Also, try not to feed your fish too much food
