A surprsing and welcome new addition into the hobby today are tank raised Pinnatus Batfish. Like mandarins, they are another of the beautiful species known to have low survival rates, and these tank raised fish will allow knowledged hobbyists to add a beautiful new tankmate. On an important note however, these new captive raised arrivals are only 3" tall, it's important to keep them in a system that can adequately handle their adult height of 18".
