    Default Emperor or Kerri tetras


    0 Not allowed!
    I'm looking to add either some Kerri tetras (Inpaichthys kerri) or Emperor tetras (Nematobrycon palmeri) to a tank that currently has only a pair of apisto cacs, one GBR, and a couple of otos. I love the color of the kerri and love the fins of the emperor. Anyone have experience with these two fish or reasons to prefer one over the other?

    Emperor tetras, are more attractive than the Kerri IMO, living up to their name with their rich purple/blue coloring and of course their "trident tail". Even the female Emperor outshines their counterpart kerri, which is usualy a plain brown fish.

    The "super blue kerri" is a very attractive color-morph, I do have to admit.

    I agree with Steeler1, Emperor tetras outshine Kerri's. They do get a little large so make sure your tank is large enough for a school.

    I too have kept both. I actually prefer the Inpaichthys kerri especially in the setup you describe. I think these would be more "appreciated" by the quieter fish.

    Nematobrycon palmeri are a bit more feisty. The closely-related N. lacortei very much so. A beautiful fish, but can be a real bully. I had a group of 12 of these, along with around 8 N. palmeri, in my 5-foot tank, and after a few weeks, I came in to see all the fish (about 100 of them, various tetras) down at one end of the tank, with two male N. lacortei ensuring they stayed there. I moved the "Emperors" (both species) to my 90g, and same thing happened, only I left them and this time they actually nipped the other fish. I gave them all away.

    My present group of 9 N. palmeri all hatched out and grew up in the 90g, after I had removed the original groups (these species are prolific spawners) are much more restrained, fortunately, but they are still a bit active so I would watch what they go in with.

    I'm going to respectfully disagree with Byron on this one; I have never had Emperor tetra's nip anything and I've kept them on and off since 1985. Even the males "mock battles" never amount to much.

    This very reputable site does not mention aggressive behavior: http://www.google.com/url?sa=t&rct=j...55980276,d.cGE
    As a matter of fact the same source claims the Kerri; can be a nipper if not kept in sufficiant numbers: http://www.google.com/url?sa=t&rct=j...55980276,d.cGE

    You must have gotten a very aggresive school for some reason.

    Thanks for the input guys. I use Seriously Fish also when researching and read the same thing - that the emperors "sparring" if any, was harmless.

    I have been leaning toward the emperor because of their fins as well as color until my LFS mentioned the kerris. He said he prefers the color of the kerri, so I'm wondering if he was talking about the "super blue" kerri. I'll have to wait until I see what he gets in.

    These will be going into a 20 gal long tank.

    Def the emperors. They have a pink sheen and look awesome with the yellow and black. Get even amount of male and female (you can tell my eye color and fin shape). Should be noted that many times the fish will look different than from LFS because usually conditions at home are better. Good luck!

    I'm fairly certain it was the N. lacortei that were the problem. What happened was that the two species got mixed at the store, and unfortunately I ended up with some of both (only had wanted the N. lacortei whic h is very rare at least here). I can assure you the males of this species were terrors. I moved them through three large tanks before putting them in a spare 20g and giving them away. My N. palmeri that appeared in the 90g and have grown up in there, and they are N. palmeri, have been fine, though they are in with m ore active fish (Congo Tetra, Black Ruby Barb, Beckford pencilfish. I see the male Emperors and male pencils challenge once in a while, but the beckfords can give as good as they get.

    Matt's comment on nipping for the kerri is basic for almost all tetra. I had 9 or 10 when I had these, in with Diamonds (which have long fins), Black Phantoms (which are sedate by comparison), cardinals, a Bolivian ram, dozens of corys, etc, and never had issues. The kerri are more active but kept to themselves. The blue sheen on the male is quite striking, a metallic hue, making it more of a "noticeable" fish than the Emperor.

    That is not sufficient space for Emperors in my view. Mine are in a 4-foot 90g, and I wouldn't have these in anything less than a 3-foot tank. You want/need a group, 7+.

    As I mentioned in my last post above, the kerri is more colourful. The blue metallic sheen that the male has is quite stunning. Your fish fellow is correct this time.

    Byron.
