what are they?

[elltee]

Woo first post
Bought these as a smart looking tester if you like for the tank. Now i wish it wasn't quite an impulse buy. I like them alot but i need to know what they due to behaviour. believe thy are a breed of tetra?
i have two of these that spend alot of time side by side as if they are leaning on each other.
Could this be mating, fighting off males for female attention or territorial
this is my first tank so any knowledge is helpful.
Cheers

Those look like penguin tetras. I'm not sure what you mean by 'smart looking tester', but if that means you didn't cycle the tank, you're in for some water changes- I just learned about cycling but I already have fish. What now?!

they are black neon tetras not peguin tetras, they dont have the black continuing on the tail.

I say they are pencil fish

They look like they could be flying foxes especially by how u talk about how they are acting

 

[Aquadestroyer]

Not with the red on the fins, they very well could be fighting over females

Didn't see the red looking at the pic on my phone lol

the 2 on the right are definately black neon tetras. i cant see in the picture but they have redish/orange color over their eyes.

go to aquahobby.com and look at the golden pencil fish in the gallery section

Look like pencilfish to me also. They are not stocky enough to be black neons, and they are definitely not penguins.

What a difference a full size screen makes. Looking back, they're not penguins for sure. I would agree that they look like pencilfish.

Sorry for the late return. They are indeed Golden Pencilfish.
