Hi Valerie:

Perhaps it is time to start acclimating your fish to brackish water. This will depend on its size.

When very small (under 2") they can do fine in fresh water, but once they grow larger they will need Brackish, and when full grown will thrive in Marine conditions.

I wish you luck with all your marine aquarium endeavors.

I possess over twenty-five years of hands-on experience and knowledge in the ecology of aquariums. Beyond the traditional, I have successfully tested and sustained environments that have been uncharted territories for hobbyists, for decades. I am the first to admit I don't know it all because there will always be something new, amazing, and exciting to learn about, as discoveries are made. It's a hobby one can never outgrow, or grow tired of.

After High School, my experience and love of marine animals influenced me to take up studies in Marine Biology. Throughout college, I studied Microbiology with an emphasis on Marine Life, as well as numerous other sciences. I continued to advance in this hobby, by building a dozen or more saltwater ecosystems all utilizing Microbes as the major source of my filtration method.
