Dave/Devon, thanks so much for the response. If this female was able to spawn with one of my males are you guys saying the traight would not be passed to the offspring, I was under the impression it would?

I'm confused.. :(


I'm not sure, if it is genetics, then yes there is a possibility it could be passed down to some of the next generation (if it's a recessive trait, then it won't come up as often in the young, but if it's dominant, which i doubt, it would show up more in the offspring). If it isn't genetics (like previous injury) than it "shouldn't" (not too sure about that) be passed down.

My guess is that it is in her genes.. I wouldn't let her breed.

What are the odds that she happens to get an injury that caused both nostrils to appear that way?

I had a juvi altifrons that had white bumps sticking out of his/her nostrils, unfortuanely s/he died a few weeks after I noticed it.

Thanks for the reponse Eric. It was no injury or HITH or anything like that, like you said what are the chances of it being caused exactly the same on both sides. It has been that way and very noticeable at a young age, like 1". It gets smaller, as she get larger like she is growing into them but I know it will never go away. I'll see if I can drum up a pic of her as a juvie.

I am curious how or why it happened. Anyone else have a photo of a similar nostril issue?

(I like the Satanoperca X-ray pic in your avatar BTW, very cool :D)

That was exactly why I ruled out injury from your female and my old juvi alti, pretty darn rare to get the same injury on the exact same spot on each side.

What are you planning to do with the 300 that you really don't want to put her into it?:D:nilly:

I guess you won't know if it's passed on unless you bred her. I had a weird female severum that had a strange shape and gray color. She spawned with a nice turquoise male and I raised out a group of fry, only to find they turned gray and ended up with her same strange shape. I ended up culling them all at 3". :( Up until that size, they didn't look anything like her, then they just kind of morphed into it over a month or so.

To be on the safe side, it's probably best to just avoid spawning her.

Your 100% right Ryan. I don't want to risk it either and I'm not really interested in raising fry to find out. I'll jst move her. The wife is pretty set on keeping her.

Eric, no plans in particular just like to keep groups together if possible.
 
i think theres a chance that it would be passed on to offspring in the same way that any other unusual trait would, super long streamers/color variations/size etc.
 
If the fish is healthy culling would be a stupid move.
 
You guys make me sick. Killing a fish because its ugly. Even if you are breeding fish for profit still pretty heartless. Kudos to your wife for exploding at you. If you really don't want the fish to spawn, separate it or give it away!!!!
 
If your question is should you euthanize the fish, then the answer is no. even if it is a genetic trait, it is likely a recessive one and won't be passed on to offspring. if you don't want the fish breeding, move it to another tank, or give it away. killing a perfectly healthy fish is a ridiculous idea.
 
I don't do it myself, but it is not that controversial of a concept. when animals are bred for specific traits, it is quite common to cull the ones that won't pass on that trait . . .

might sound a bit harsh, but it's part of the business . . . and in the long-term, it improves the stock . . .

it should always be done humanely, of course . . .
