Hello,

I was looking through here, and I do have to admit, at one point or another I have had knifefish catch my interest. Considering the size of tank that I will soon have (75 Gallon), what would be the smallest species of Knifefish out there?

Thanks,

Shane, :headbang2

The smallest I can think of is Xenomystus nigri (African Knifefish). It generally will be 8" but said to reach 12"

Not a good choice.

I've seen 2-foot long Eingenmannias caught by fishermen around... They get BIG, although not heavy-bodied. BTW, most captive specimens don't live long enough to grow up.

Best regards.

You could get a small black ghost knife.
By the time it starts to outgrow the 75g, you'll be old and have a few 300g tanks laying around the house. :D

Centipede Knifefish aka Mottled Knifefish.. Steatogenys elegans

They claim to be up to 12" on some sites, but I thought they maxed around 8"? They are a nice peaceful knife however.


Daniel~ Very awesome info on the Green Knifefish.. I just got a batch of babies in stock, and its saddening to know that. It would be awesome to see some pics of yours!
