This is larger type of woodcat that can reach an adult size of 11-12" in captivity. These are a more active woodcat and when kept in groups of 3 or more. While larger Fisheri Woodcats will eat smaller fish that fit in their mouth they are a peaceful fish for their size. One of the features that attracted us to them is that as the males mature they develop an unusual dorsal fin as you can see in the picture. These are easy to feed fish that will literally eat anything that you offer them. While they do adapt to a wide variety of water parameters they prefer a soft water with a pH of 6.0-7.2 and a temperature of 78-82 degrees.
