Hello,
I want to startup a small (around 20 gallons) freshwater tank and have been reading the boards for advice and suggestions. I wanted to know what people thought about substrates. Gravel or sand? What are the pros and cons of each? What types of fish thrive better in each substrate?
Thanks for all your help.
