Knifefish in Captivity

I saw a new species of knifefish at the fish store today, the Brown Ghost Knifefish, Apterontus leptorhynchus.

 

I've seen;

Notopteridae:
Chitala chitala
Xenomystus nigri

Gymnarchidae:
Gymnarchus niloticus

Gymnotidae:
Electrophorus electricus
Gymnotus carapo

Apteronotidae:

Shedd aquarium keeps
South American Knifefish:
Black ghost knifefish
Electric eel (Electrophorus electricus)

Featherback Knifefish:
African knifefish (Xenomystus nigri)
Clown featherback Knifefish (Chitala ornata)

 

The ones I’ve seen most in public aquariums/pet shops are the species in the genus Chitala, Electric eel and the Black ghost knifefish.

 

I have seen electric eel, like most, along with black ghost and African brown. I have also seen clown knife in the pet trade as well.

 

There's an online fish selling site in the UK who has or has had clown knife fish normal and albino , black ghost ,electric eels and banded knife fish for sale
