they can be 49cm.
I would be very carefull what I put with a Black Ghost Knife Fish. If a fish is small enough to fit in its mouth them it will be eaten. Bettas are a nice little morsel for them. I guess fully grown Angels, Discus, Plecostomus etc would be OK. Don't forget some of these knife fish can get BIG around 24 inches. That means a big tank and a big mouth to feed.
If you are asking about the Black Ghost Knife fish they are natural predators and their prey is any fish small enough for it to catch and kill. They also have the ability to electrocute a fish to stun it. They will kill neons and guppies but mollys may be a bit big for them.
there is no such thing mark my words you need to check another website this one is absoulutley disgraceful!sweenytodd repliedActually there is. The Black Ghost Knife Fish. Apteronotus albifrons is a nocturnal, passive electrogenic fish from the Amazon, that grows quite large. It is fairly common in the aquatic trade. Maybe you should research before you post an off the cuff reply and assume that a site is "absolutley disgraceful!".
I have heard it can but i also heard it cant... i honestly just care about its tankmates,how big it gets, and if it has a decent amount of room to swim... a 40 gallon that is lightly planted with many hiding spots is a well suited environment for a black ghost knifefish! im also thinking of getting one :)
They are about this big | |
To my best knowledge GK's will we anything smaller then there mouths. So if your going to get tank-mate for it get something that it can not eat. And make sure your tank is big enough for both fish. 150 gallon of something close to it so the GF doesn't feel threaten or he will kill anything or possibility die of stress himself.
