Elephant nose fish are amazing creatures, I have had the privilege of keeping up to three at one time and they seemed to get along just fine, even in a tank that had limited hiding places. The elephantnose are passive fish and can be taught to eat from your hand, I actually got mine to lie in the palm of my hand. Warning!!! DO Not introduce a black ghost knife fish to a tank if your have elephantnose fish or your fish will suffer the same fate mine did, 1 blackghost knife fish, 3 elephant nose. One by one I would find them stripped to their skeletons at the bottom of my tank, I initially though it could be my tiretrack eel until I found the Black Ghost dragging the remains of the last elephantnose to it's hiding place.. Otherwise the fish are amazing..

Don't feed petersi tubifex worms, or any other fish for that matter - they are full of bacteria and other harmful stuff. I breed these fish and do behavioral research with them and they are quite charismatic. A few words of advise - keep tanks completely covered or they will jump, change water at least once a month, and give them plenty of room. Similarly, if you only have 2 of them they should be kept separate, 3 or more can be together - these fish are very territorial.

I've had my Elephant Nose for two years now. He eats nothing but bloodworm, preferring the frozen type to the live. During the day he disappears into his lair, but is very active at night. In order to make sure he doesn't starve I feed him at night. He'll come to the surface and take worms from my fingers. He also likes to play with the worms, blowing them out of his mouth and flicking them around with his trunk. He's survived some major water poisoning disasters (which put paid to a large sailfin pleco) and seems to be very hardy. You have to make sure that the other fish don't eat all the food, because the Elephant Nose is not very competitive and is a slow feeder (hence the feeding at night). The only other "essential" is somewhere for him to hide. I'd recommend them! Anyone who's got any Elephant Nose tips, I'd love to hear them.

I had my Elephant Nose for 10 minutes before he jumped out of the tank (lesson learned)we were able to get him back into the water without too many problems and he has been quite happy ever since. I have read (after the fact) on a few web sites that these fish like to jump, so I would recommend that you cover any openings in your tank. Also when he was first introduced to my tank he bumped into every fish I have - knocking them around and establishing his territory. I don't know if I bought a spunky fish or what but he really likes to put the others in their place. My other fish don't seem to mind it and overall he's a great addition to my 32 gallon. I've given him plenty of places to hide during the day and he's all over the place at night. I feed him the frozen blood worms at night and he seems to be getting plenty to eat. I'm training him to eat from my fingers and so far so good. I hope others are getting as much enjoyment out of their Elephant Nose as I am!

Yup...jumped out of my tank in the first half hour. But has been a great addition to my community tank.

My Elephantnose spends most of its time during the day pretending to be a leaf... he gets right up next to leaves and matches their angle (sometimes even upside down) and stays motionless for 10 or so minutes. There are plenty of better hiding places in the tank, but he defiantly prefers to use his cunning (or so he thinks) disguise technique. He also spends a lot of time leaning up against my Dragon Goby... they sometimes pick a hiding place together and sit there peering out from it. He is always... day or night, doing something worth watching, a real character of my well stocked community tank.
