Any Gymnothorax Polyuranadon keepers?

Recommended Posts

In wondering about what you're keeping I found this on the internet about feeding Tiger Morays- I thought it was interesting: 

Feeding the Tiger Moray is just like any other moray eel. Reports of them not eating, or not gaining weight in freshwater have been shown to be without basis. While some aquarists have had trouble getting their Morays to eat, the salinity of their environment has been scientifically demonstrated to not be a factor. Tigers can go without food for extended periods of time, with some evidence that they could live for up to 4 weeks without food, this being said, that should not be any aquarists goal for successful husbandry. We suggest feeding smaller specimens every other day, and larger ones on a weekly basis. Meals should consist of a variety of thawed seafood, cut to a size about as big as the moray-in-question's head. All moray eels have notoriously poor eyesight and hunt mostly by scent. Aquarium environments that have lots of powerheads, or lots of food in the water can be confusing for a scent hunter. Feeding with long tweezers or feeding sticks is a great way to target feed your eel. While it is possible to train morays to eat from your hands, you should not do this. They have a very toothy, painful bite, and a rather noxious mouth. Many aquarists have reported these bites to be painful for up to 24 hours and prone to infection after that. Whether or not this is the result of venom is debated, but in the real world, this seems academic. Don't hand feed eels.

What if my Gymnothorax polyuranodon doesn't want to eat? In house, these eels eat pretty well for us. But even picky fish can usually be induced to eating with live food. Mollies, guppies and feeder shrimp or crayfish should all be taken with gusto. Keeping your own cultures of these, or acquiring them from known cultures pretty much eliminates your risk of introducing unknown ailments to your system. Feeding them at consistent times will have them recognizing you as a food source in short order. In time, they should segue off live food without much issue. Attempting to feed them at night, when they would naturally eat, can also help segue them over to thawed foods.

On the topic of feeding, well fed specimens have been kept with other fish long term with mostly no issues. However, some individuals seem to consume tank mates regardless of how well they are fed. Keeping them with larger fish will reduce this risk. Avoid housing them with overly aggressive fish, as Moray Eels look all toothy and tough, but are actually very passive fish that can be picked on which often results in an eel that won't come out for meals. In our experience you can keep multiple Gymnothorax polyuranodon together as long as they are introduced to the tank together and are all a similar size. Most cleaner inverts will be eaten, but snails and hermit crabs seem to be the longest lived.
