Hello, a few months ago I did an experiment with a local pipefish species known as the Gulf Pipefish that according to some online sources, such as FishBase, floridamuseum.com, Wikipedia, and more inhabits freshwater streams, lakes, and rivers. I attempted to acclimate it from brackish to a freshwater environment-- it unfortunately failed. However, with the knowledge I have gained since then, a second attempt would likely be more successful. So, it will likely be MANY months in the making, considering seasonal availability and the delicacy of the process, however I may try again eventually and when I do, I'll share pictures.
