Are male swordtails supposed to be aggressive? Mine is being very aggressive and territorial. Please help because I don't like the aggression in my tanks.

They can be.

Try to have multiple females per male.
Also, break up the fish's line of sight as much as you can with your decor.
What they cannot see, they cannot hassel.

Tom

But there is plenty of stuff to do that. And what is strange is, he is scaring my kribs and my kribs are trying to hide from a little fish that is just over an inch long. I might take him to an auction in January, so I don't have any more of his shinanagons(?).
Tom

Dino

Sounds like a good idea.

Just a question, what is the temperature of the tank?

Tom

Just let me go check, I think it is at 81F, but I may be wrong, hold on.

An exact 80F. Why does it matter?
Tom

Dino

At higher temperatures, some fish become more aggressive.
I have observed this in both cichlids and livebearers.

Your temperature should not be a factor, though.

Tom

That's good.

well he could be proving his dominance in the tank
i have a mollie that does that
if u want u could put him in a breeder cage for a few days to isolate him from the otherss and then let him back in after a few days, he should be fine then

wat kind is he?

Tom

The store said he is a neon swordtail. Here is a pic of him.

The pic is old, he has a larger 'sword' that is orange with a black line along the bottom of his tail fin.

He's awesome. We're just first getting some different swords again. For about three months we only had red and wag swords.

Tom

I got some(2) female friends for my little guy since he is still really aggresive. The females are koi swords and ready to drop some fry any day now, they came that way. So after that, the neon and koi can breed and I can get some interesting swords. I'll keep you guys posted. I'll also have pics asap.

i liked the male koi spikes but i don't like em too much mainly cuz of their eyes. It reminds me of albino fish...which I'm not a big fan of.
I've got a female orange mickey mouse sword about to drop...I can't wait. The males I got with her are a red sword and a redish-orange mm sword whose startin to get black in his tail

Tom

Can't wait for the fry for both of us to get here. I'll have you a race, report when the fry get here and back it up with pics, and the loser has to tell when they get here and has to show the pics of the slow ones. lol
