Long term captive male frogfish for sale approximately 4". I've had him for almost 2 years now. Keeping him in 1.005 salinity, salt is so low, java moss and freshwater fish will thrive but this species cannot survive longterm in pure freshwater. I've been feeding him predominately ghost shrimp (from the local marsh) and striped killifish as well as other feeders. I was not able to convert him to frozen food. Let me know if you have any questions.
