This month were taking a closer look at Erythrinus erythrinus also known as the red or hi-fin wolf fish. Originating from the freshwater systems of central and South America, this particular wolf fish has found its way into the living rooms of fish keepers around the globe despite being fairly uncommon in retail fish stores. Feeding on smaller fish and insects in the wild, the wolf fish is a true predator, however will consume most non-live foods, but of course will appreciate a feeder fish or two if you have the resources. As we continue our talk, watch as this one chows down on a live meal.

      The red wolf is one of a handful of fish in a family consisting of three genera, all of which are extremely aggressive. Another member of the family is the much larger Hoplias malabaricus. The red wolf will grow to a max size of about 8 to 10 inches, still making it quite a large fish, but not unmanageable if you’re determined. Caring for this fish is relatively easy, as it’s fairly adaptive in the home aquarium. Preferred by this fish are the following water conditions: A Temperature between 70 and 80 F, pH anywhere from 6-8 and 3 to 18 degrees GH and KH. If you plan on keeping this fish long term, a minimum tank size of 55 gallons is recommended, if not a 75 or larger. Filtration must also be kept in check as this fish will generate a lot of waste especially if you’re feeding it live and or high protein foods on the regular.
