What kind of tetra?

[SRG66]

Hi Everyone! What kind of tetras are these? Thanks for your help.

I am NOT an expert at fish identification, but if I could make an amateur guess, I'd say penguin tetra.

They look like emperor tetras to me. If your fish are fully mature, it appears you have all females.

Okay, yeah, after comparing some pics I'm inclined to agree with @connerlindeman.

I think they are Inpaichthys kerri Gery & Junk, 1977. The usual blue hue is not always strong. If you do a search of images of this species you will find identical ones. This fish has common names, one of which is "blue emperor" so the suggestion of Emperor Tetra is not too far off, they are frequently confused.

How many do you have? This is crucial as this species is active and may turn nippy with insufficient numbers of its own species.

Thank you for the info! I have 6 of them. I was trying to learn about these, and the similar ones that seem to be called the same names interchangeably by some people. It was hard to get info that was consistent across different sources.

I agree with @connorlindeman, they look like emperor tetras.

If you intend keeping them, definitely another six, for 12 total. This applies to the regular Emperor too, should you still think that is what you have.
