Enoplosus armatus is the only species in the family Enoplosidae. This "Oldwife" was a "new" addition to us and we were very excited to be able to enjoy it!. They are rarely available - this is the first one we've been able to get.The name "Old Wife" was given in reference to the sound it makes by grinding its teeth after it is caught. The Old Wife is easily recognised by its distinctive shape and colouration. It has a deep body, and two separate dorsal fins, the second fin is sickle-like. The body is silver-white to brown and has six to eight black bands of variable width. Juveniles are more elongate than adults and have a blotched colour pattern and a white-rimmed spot on the soft dorsal fin. The Oldwife makes a nice addition to the marine aquarium. They are interesting to watch and easy to keep! Dorsal spines carry a poison, we assume it is similar to the lionfish, but this is not confirmed. For more Information on keeping marine fish see:

The Oldwife is easy to keep. They will readily eat most anything you feed them.
Maintenance:
Feed all kinds of live, frozen, and flake foods. It is best
to feed small amounts several times a day. We generally feed squid, shrimp
(the same kind people eat), mussels, and all kinds of chopped up fish.
A good vegetable formula like Formula II is also beneficial.

All kinds of meaty foods and greenstuffs. A bottom feeder.

not. Keep an eye on newcomers and established fish in the aquarium.

| Old wife are found along the east coast right up to southern Queensland. They are supposed to be really common but i haven't seen one yet. p.s. i thought they grow to 25cm, that's what it says in my Australian sea fishes book.

| Just like to add that these fish are not limited to South Australia. I have been snorkeling on the NSW coast and frequently encounter an old wife. The other posters statement is true, they are very timid and every time i see them while snorkeling they seem to hide/hang around weedbeds

| Some of the coolest comments: |
| hello, I found out that they are sometimes extremely timid, I tried to feed it live fish and it ate it with no problem. I have a rather small tank so my 2inch old wife could catch its prey( they are very slow!) 2004-01-17 |
| Hello, I have an 2inch long old wife and it sometimes eats plankton. It is not taking flakes, but I hope it will soon.
