Hello Everyone, I kind of got into the tropical fish thing by accident. My Mother-in-law bought our son a Betta a while back, for bringing home a good report card. Anyhow, since then I've become obsessed. I didn't like that he was in a 1 gallon bowl, and have since moved him into a 10 gallon tank with a power filter. He seems to be really enjoying that much more. He is WAY more active than he was in the 1 gallon bowl. While we had the 1 gallon going for a while, I've only been running this new 10 gallon tank for 3 days now. The water heater is keeping the temps at 77-80 degrees, which I read is perfect for tropical fish. I did a water test kit and everything was perfect minus the ph level which seems kind of high. The ph level is 8.4 and to be honest I'm not sure how important that is as I've read conflicting info all over the internet about having the ph anywhere from between 7.0 to 8.6 for a tropical freshwater aquarium. Unfortunately, I wasn't aware of the nitrogen cycle until after I put in my fish, however I do think I may have prevented a cycle because I brought everything over from his 1 gallon bowl (water, gravel, props, etc..) though I still plan on using some Tetra SafeStart to help make sure things are under control. I have been testing the water daily just to keep an eye on it and I'm already seeing nitrate at about 15ppm which I read is really good. Today I plan on buying some ammonia tests to keep an eye on that as well, as I'd hate for my fish to succumb to death. Anyhow, the reason for posting is, I got the 10 gallon with the hope of adding more fish. Perhaps tetras or something? Is there any other considerations I am possibly overlooking before I can add more fish? If so, what are they? And lastly, what types of fish could I safely pair up with my betta? Thanks, and sorry if I seem too clueless, I'm eager to learn and find that this is a VERY fun (and dare I say theraputic) hobby so far, and please feel free to tell me that my plans are stupid...I just want to learn.
