Tetras

[Errbill]

If water parameters and tank size etc weren’t an issue which 2 types of tetra would you keep together?

[Stephen]

It would depend on the tank water temperature and what other fish you have.

[Pleco Fan]

I have cardinals and harlequins.

[SPACKlick]

Serpae and Green Neons. I think the bright Red and stunning blue/green shimmer would contrast really nicely. It's doable in a soft acidic dark tank.

[BalloonMolly]

Blue + Glowlights, probably. For very similar hue-related reasons as above.

I saw some tetras at wildwoods Enfield yesterday which looked like oversized black neons with a flash of yellow on their sides. Can’t recall their name unfortunately. They were pretty big for tetras, Congo sized. So them and congos if I had the space.

There’s a few new Moenkhausia spp that sound like that. I have a hunch you might have seen one of these two…

If it’s not them, try M. heikoi and M. phaeonota.

[mikeyboy123]

Heikoi most similar to what I saw. Not 100% it was them though.

[plankton]

Lemons and rummynose (which I've had in the past), or, for a bigger tank, emperors and Buenos Aires (I've had penguins and BAs but have decided that emperors are more favourite than penguins).

[Si4geckos]

Probably the ones I do have. Cardinal tetras and albino congo tetras
