I just bought my first fish tank ever, and have my first two fish ever... I have 2 goldfish starter fish in a 10 gal. tank. It's about 4 days into the "cycling" process, and I'm not so sure what to expect... I'd like these little guys to survive. The place i got the setup from said they wouldn't sell me any regular fish until my tank has cycled for like 40 days, and they can get a water sample from my tank. I have a marineland 100 power filter, and an aerating setup, and thats it, aside from the light. Any information and advice would be greatly appreciated. also, let's say i went outside and gathered some rocks, how should i treat them before placing them in my tank?
