I inherited a fish tank from a friend and this fish was tiny at the time. Four years later, he is huge! I recently learned he is a Picasamus and that my tank (20 gallon) is way too small for him. I don't have the room or the money to keep getting bigger tanks as he grows, as I have read he can live 10-15 years and can keep growing! Does anyone have any suggestions on how to re-home him? I am in the San Francisco/Bay Area and not many people have enormous tanks in their houses here so asking around for someone to take him has not worked so far! Do fish stores ever take these guys back? I feel bad keeping him in such cramped quarters. Any advice?
