I think they're trying to mate, but I dont know.

Two of them have developed black markings, one more so than the other. It's actually really pretty.
The two with black markings are chasing after the one with no visible change in coloration. So I assume, maybe the ones with the stripes are males, and the one with none is a female?

They chase the one around, and will one in a while vibrate against each other while swimming.


Is this a mating thing?


It is kind of funny, because they have been ripping around the tank none stop! My oscar and my jack dempsey have just sat in the corner watching them, they almost seem exhausted from the dollars lol

It kind of sounds like the vibrating thing may be a sign of mating, but I haven't read anything about the change in colors.

Here are some pics.

Black tipped fins are usually a symptom of fin rot. Keep an eye out and make sure it's just a colour thing, and not anything more serious.

Edit: I just re-read what you said about the vibrating thing. My tetra's do that all the time. Sometimes three at once. They've never had babies though.

It's not fin rot, since its not only their fins. They get stripes on their bodies and their fins when they get excited or what ever their doing.

Yes it is mating. The black streaks and dots are prominent during their mating and their swimming side by side is also. One is dropping eggs and the other is fertilizing them.

Cool, thanks! That clears up my confusion, hopefully they dont succeed though. They do share a tank with an oscar... And a jd. It would be sad to see fry gone the way of a snack.

My SD's are all females so that explains why yours have stripes and mine don't. Never seen stripes on SD's before.

Yeah, I never knew they changed color. But after they settled, the one got nice big spotted stripes going. Then last night when I posted this, their tails had black on them took, looked awesome!

It's really nice! I just wish the two males facial wounds from the previous owner/tank would heal. Maybe its scar tissue on his face now and it wont come around.
But i guess it has only been two weeks in clean water.
