just bought a long-finned zebra danio today. I put it in my tank and the danio was cheking it out. I leave for a few minutes and when I come back, the danio is chasing the long finned. I don't see any white bumps on the gills, but I can't tell if this is aggressiveness. I've looked on the internet but nothing is helpful. I've seperated them. I don't have access to any more danios, so I cant get more in my tank. O ya, the danio is also seems to target the long fin's back fin. And a few days ago 2 of my guppies died due to direct sun. Could seeing his friends die influence this behavior? Is it ok to put them together again? Will they kill each other? Are they mating?

I changed the eniviroment of them (moved the castle around and the plant) and they are behaving a little better. O ya, the breeds are
Long-finned zebra danios
and
zebra danios
The long finned one's belly is like flat then scoops down.. kinda like an upsidedown mountain and the other one's stomach is just flat.
They won't stay still long enough to tell from the stripes about there gender.
The tank is 12 inches by 6inches

If I can't get another fish, I am
A) gonna offer people I know my new fish
B) Offer it to the local Middle school because they have an agriscience program in which kids enrolled in it get one free zebra fish....
I don't see why one won't hide in the castle...

Just Wondering, Are There Any Other Species Of Fish (Other Than Danios) That Would Stop The Bullying?
2007-12-01 11:16:46 · update #3
Danios will always chase each other--it's just their nature. However, this can be stressful if you've got too few of them, since they're schooling fish. I had a bully danio of my own, a long-finned gold, which was always chasing my two other LF golds around. I've since added two long-finned zebras and things have settled down nicely.
If you can't get more danios, you may have to separate the bully into it's own tank permanently.
And no, the loss of the guppies has nothing to do with it.

Danios are a social fish and are more comfortable if they're kept in a school. Then they would work out a pecking order among themselves. With just two fish, if one wants to be dominant, it doesn't have any other fish to pick on but the other of it's own kind (or other fish in the tank). If you get a few more danios to bring the total up to 5 or more, any aggression will be spread out within the group so no one fish gets picked on all the time.
In danios, you want to look at color and body shape to determine the genders. Females tend to have rounder bodies (they carry the eggs) and don't have as intense of colors as males. If your danios are zebras, males will have a yellowish stripe between the black and white ones. And it's the females that tend to be the more dominat fish in this species.
Seeing another fish die probably isn't responsible for this, but you should keep sunlight off the tank. It not only can raise the temperature of the water, but it can cause algae to grow. Light triggers spawning in danios, but just having the tank near an eastern window so the fish can tell day from night is enough.

one danio is constantly chasing long-finned danio. Aggressive or Mating? I have 2 fish.?

Danios need to be kept in schools. They will keep this up until you add more danios. They won't kill each other, but the mean one will make life hell for the other one until the situation is fixed. If your LFS doens't have any danios right now ask them to order some for you.
As for the guppies dying, I doubt it was because of direct sunlight. In nature, guppies live outside with the sun shining down on them all day long. A description of your tank setup would be helpful to figure out what may have happened to them.
Whatever may have caused the deaths, I doubt your surviving fish are traumatized. Sorry, but they just don't have the mental capacity for emotions.

You should know, danios are fin-nippers. The danio was probably trying to nip the fins... It could put a lot a stress on your long-finned zebra.. You should keep them separated so one of them doesn't get killed.. It would take a long time for fish to mate.. my guppies took a year or so to mate.. now I need to figure out what to do with the babies! I've never heard of fish dying from direct sunlight...

Ashley is right. Danios are schooling fish. When they are kept in schools, stress levels are minimized. Individuals faced with what is perceived as a threat automatically go into fight or flight. Without a school to evade into/with, the option left is fight.
What size tank are you housing these fish in?
Call local pet stores and find more danios if your tank is large enough to house more of them.
