Advice: Research Research Research!!!!! you can't read enough! & don'talways believe what the people working at the pet store say - they don't always know the facts!
Don't feel bad if a fish doesn't work in your tank & you have to take it back to the store - its usually the best thing to do rather than having problems!
About Yourself: Have had betta's in the past a year ago decided to get a small tank & pretty soon was additcted to the hobby!!!
Also never knew I was a goldfish person & have since changed my tank into a goldfish tank :)
