Goldfish and tankmates

[AAJ]

I have a 10 gallon freshwater tank with 2 quarter size Goldfish and eight 1 inch Zebra Danios.

My first issue is that of ammonia buildup. I find myself doing a water change several times per week as the levels rise to 0.5 quite quickly. I've taken the advice of our local pet shop and added BioSpira to help speed up the development of the biological filter but it hasn't seemed to help. What should be my maintenance schedule and what activities should I be performing?

Secondly, the pH of our town water is always 7.0 and the tank initially appeared to hold this pH. In the last few weeks, the pH has droped to 6.4 dispite all attempts to hold it at 7.0 I know that Goldfish prefer a pH higher than 7.0. How do I correct this situation? Should I correct this situation?

Thank you for any advice you can offer to rectify this situation.

Well Goldfish are known for producing a lot of waste.

Goldfish are also a cold water fish and Zebra Danios really aren't, so that doesn't really work out. Not to mention Goldfish shouldn't be kept in that small of a tank.

If I put the goldfish in other quarters, what other fish could I mix with the Danio's. I like the activity of the Danio's but need to add some color.

I'm not positive but I think danios need atleast a 20 gallon tank. Not sure though

Yeah I'm not sure either, not exactly big on danios in the first place

Cory Cats are a good bottom dweller that are cool, not really that colorful though (depending on what you consider colorful).
