Hi All,

I have a male betta fish, 2 neon tetras, 1 tiger tetra and 1 black tetra and they seem to all get along. My male betta fish is so friendly, he is one of a kind. He even lets me pet him!

The black tetra, is a little aggressive towards all of them. I saw him nipping on my betta fish yesterday at his tail but my beta just turned around and swam away like it didn't bother him at all. I just added the tetras last Friday (halloween) and at first the black tetra was calm and now he is starting to get on my nerves.

All I have to say is if he keeps being mean to the other fish, my cousin has a lion fish and I will feed him to the lion fish! ha ha ha =)

Black tetras are nice looking but be careful with them because they can be aggressive.

    You should go to your fish store immediately because it might have either a parisite or a bacteria.

I used 2 black skirts to stabilize my first 10 gallon tank, and they got fairly aggressive. The only things they didn't eat were bottom feeders. After I upgraded to a 25 gallon tank though, and added a whole school of neon tetra's, they finally quieted down.

I have a Blackskirt tetra. I named him Zippie. He got that name because he zips around the tank. I have Zippie in with my 3 goldfish. They get along just fine. I love to watch Zippie swim. He makes me dizzy. I think the Blackskirt tetra is cool.

I have a 10 gallon tank which includes two cory catfish, one Chinese algae eater, one female betta, and Angelique- the fin-nipping bully. I was wondering why Rose, my betta, would puff out her cheeks and fins like a lion and charge Angie- then I caught Angie harrassing Cory & Harold (my catfish) last night. She has been an absolute terror. She even bears her teeth and chomps them at me (so it seems). I know you all have said this behavior is fairly harmless, and in fact, Rose still has all of her fins & no one looks nibbled upon, but I am worried about their stress levels. Stressed fish are not happy fish. I think I will try some of the advice I have seen on this page and get her a companion. At the worst, they can batter one another and leave everyone else in peace.
Yeesh. What a soap opera going on in the fish tank!

I love these fish! I've had a school of these fish over five years & never lost a one. Even after a November icestorm where the the little guys were left in 40 degree water for five days they all survived & kept on kickin' even when everything else except my sisters white clouds died. A great fish indeed.

i just put some silver dollars(2) into my 55 gallon tank which already had a school of 5 black tetras who i had had for over a year... although the dollars are a bit bigger the group reminds me of the dr. zuess story..... tetras w/ strippes upon thars.. after a month they think they are all one school...
yes a bit testy 2 new fish but a great scene as they drag their long fins thru my real plants...

OMG the perfect tank mates for Kribensis! These guys are super fast and quite comical (Makes me dizzy trying to keep up with them when they quarrel at feeding time!). Since these fish don't just stay on the top, middle, or bottom of the tank they keep my Kribensis on there toes and keep the tank entertaining! Thank God these lil guys don't get any bigger than 2 1/2 inches...I'd be scared to feed them! And definitely keep them in groups!

This was my Scout Fish for my 20 gallon aquarium.

My friend Meagan would come by and laugh because it was such a tiny fish in such a humungous aquarium.

I named her Luna.

I can't say she's much of a tail nipper. At first, she curiously nipped at Angelito, my angelfish's, tail, and at Rey's a little bit, too. (Rey is a Powder Blue Dwarf Gourami who want a girlfriend...). She doesn't do that anymore. Instead she tries to break up fights between my demonous Kissing Gourami, Mina, and my poor helpless baby angelfish, Angelito.

Luna is a great fish. I highly suggest getting a Blackskirt Tetra for your tank of any size. They may be known to nip tails, and steal other fishes food (Luna sure does ^.^), but they're great and by no means heinous.

these fish can be total tyrants. though they are alright with the same species and other tetras, they can totally dominate other slow movers, ESPECIALLY BETTAS. more than likely fish with long fins will not have those long fins the next day. they pick on newcomers too. they are an easy fish to keep, very hardy, and no special care required.
