Ok guys, so, i dont have him yet, but i thought i would warn you that i will be posting lots of photos of this quite rare 'Tetra'.
Eventually, hopefully, he will get to about 16 inches and command a 6x2x2 on his own. Hes at work right now, and is about 3 inches long. These are a very active wolf fish in comparison to the likes of Hoplias and Erythrinus, common name is the Gold Wol f Fish or black lined wolf fish. I will be bringing him home on saturday, so prepare for pictures!

The link didn't work either, photobucket seems to think you've moved the photo. I always use the second link option that photobucket gives.

Tried sending you a mail, is your box full?

riri,
the black wolf is Hoplias sp. Black...totally different really, although they are related...they are actually quite rare are the blacks, so good find there.
Hoplerythrinus are a bit more aggressive than Hoplias - so ya, you know how that goes!

Curious, will it be "tanked" alone? Since it's more active then the "common" wolf fish, what can you tank with it? Can you tank anything with it?

Kelly,
Might look at some sort of larger catfish or eel to go with him, but realistically anything sausage shaped or smaller than him is definatly out of the question...
Size is being debated at the moment. Realistically i think its going to stay about 10 inches, thats the largest anyone has ever seen.

heh he is pretty cute right now!

similar markings to flying fox and SAE, I wonder if anyone managed to get one by mistake, probably not based on behavior, but some CFS can be really bad for keeping their fish right. Granted I woudn't think a chain would be carrying such fish.


That green spot on the gill keeps making me think he's got a little leaf stuck on him

What's the growth rate? If it grows as fast as an Oscar, can you find a cat to match? Any predator cats will try to eat him first. I don't envy your new trials and possible error on matching up a tank mate.

What size tank do you have for the cute lil' man eater and his possible new accomplice...err tankmate?

He's all alone in his 70 gallon or so (poss 75? 4x2x2). Predatory cats dont all come in as adults, so if i can pick a juvie up i'll be fine/ Growth rate is undetermined. Not much (if any) information online about these guys really..There are a few nice Horabagrus brachysoma in at work, dont think the girlfriend is too keen though.

Just found this.

Erythrinids are hardcore predators with an attitude to match the evil grimace. Which means that usually, these fishes are kept in a species aquarium, because they try to eat anything else in the same aquarium that's moving. At 3 inches, this fish might be compatible with a larger catfish (and if you're going to run such an experiment, pick a heavily armoured Doradid catfish covered in its own natural razor wire to deter attacks), but once it starts piling on body mass, even that experiment is one you should conduct with your eyes fully open, and be prepared for the Wolf Fish to have a go at eating the catfish. Ideally, any fish that's going to live with the Wolf Fish long term should be larger than the Wolf Fish, and similarly tough. By the time your Wolf Fish has hit 10 inches, you'd be looking at popping a 14 inch plus Megalodoras irwini into the aquarium, as the only catfish that could live with this beast. Even then, I wouldn't put it past the Wolf Fish trying its luck.

Also, once this fish puts on body mass, watch your fingers. A decent sized Erythrinid is capable of amputating your fingers if you're not careful during maintenance, the extreme case being the brutal Hoplias lacerdae, which at full adult size can take your arm off at the elbow. Never underestimate the damage those teeth can inflict - even at the size it is now, it has a powerful bite, and once it's around 10 inches, it'll have jaws like a car crusher.

To give you an idea what to look forward to, if you've seen that episode of the BBC TV series Walking With Dinosaurs, featuring the giant Liopleurodon Pliosaur in action, your Wolf Fish is going to be like that in miniature. It will cruise around the aquarium looking menacing, and that display will not be purely for show. Plus, I suspect that any attempt to wean it onto dead foods is likely to prove futile, which means you're looking at providing it with live fish to eat for the next decade or so. It makes Belonesox belizanus, the Pike Livebearer, look tame by comparison.

If by some chance you do succeed in persuading it to take dead foods, take my advice and obtain a good, strong pair of tongs for feeding. Do not even think of trying to hand-feed this fish, unless you want it to eat bits of your hand along with the actual food. Bear in mind that some of its relatives are capable of eating Piranhas in the wild, which should tell you everything you need to know about its propensity for mayhem. And, if you do ever succeed in persuading it to take dead foods, preferably administered at the long end of a pair of good quality stainless steel tongs, when it's an adult, you'll probably wind up feeding it bits of fresh salmon from the fishmonger's, or even the odd butcher's cut of meat.

Wow, you've taken on a serious aquarium terrorist in the form of that fish.
