I know so I just added the links....you can click on them now and hopefully see them.Its hard as heck to get a good picture of a moving fish,its like they know you want to take a pic of them lol

I see the links but I do not recognize the fish. I would hazard a guess as to some type of tetra

Those are called black skirt tetras..... they do better in groups of at least 5 or 6 ... keeps the agression amongst themselves instead of other fish.

Here's a link to a video of black skirts.... http://www.aquariumfish.net/catalog_pages/tetras/tetras_bigger.htm#serpae-tetras
You can see that's your fish, second video on the page. I had six, they were still kinda nippy; I bought two more good-sized ones and that seems to have calmed them down a bit. I guess they just have to have somebody to wrangle with, and if they don't have enough of their own kind they find somebody else to pick on.

I had a group of them (7) when I first started fishkeeping.... Didnt care for them. My fav.fresh water fish would have to the Rummy nosed tetra. Traded my Black Skirts for those.

Thanks for the help guys,I have three of them but I have them in a 10 gal tank.So Im not sure about adding double that...

Those actually are Long Finned Blackskirt Tetras

re : what kind of fish?

I saw the pics but can exactly say what kind of fish. But IMHO, it looks like a cichlid. Maybe thats why its attacking your other mollies.

Its a tetra, but when some tetras aren't in schools then they tend to be agressive.

 

[homebunnyj]

You may need to re-home them and get a fish that will work better in a 10g, cuz you won't be able to put anything in there without them picking on it, IMHO. Or, you could get a tank big enough to house a proper school of tetras with some room left over for something else. (I just love an excuse to get a bigger tank. )

its defintely a long finned blackskirt tetra.

ive had these in the past, and they can be very aggressive, even in a school.
much more aggressive than any other tetra's ive had in the past.

i wouldn't add anymore of them into a 10G tank though. they would not be very happy about that. mine seemed to be much happier when i put them into my 75G tank. they liked having the swimming room.
