Brown or Yellow Chromis

"Thank you for all the great articles on The First Tank Guide! They have been a great help in creating a beautiful and healthy environment in my aquarium. My fish thank you!"

"I have followed all your instructions, and I'm so pleased with my aquarium. The fish are very lively and look very healthy, the tank itself is crystal clear. [...] Once a week I exchange 5 gallons of water, vacuum the gravel, clean the glass, and [...] it takes me about 30 minutes now that I have the routine down to a science. "
