A Question About Tetras


Recommended Posts

Sorry if this is a dumb question, or if it's been asked a million times. I know tetras need a school, but does it have to be the same type of tetras? Will cardinals school with neons or does it need to be a large group of one type?

I think they just need to be somewhat alike. Exmple I dont think neon and flame tetras would work they are nothing alike.

Does that make since?

That makes total sense; I've seen some very rounded tetras that would not swim like the zippy little cardinals at all. Kind of like comparing a pearlscale and a comet; same type of fish, but completely different.

My neons didn't school with the glowlights I briefly had.

I have heard of neons and cardinals schooling, but they look so similar why not get just a larger school of one kind?

This doesn't have much to do with your question but as a curiousity I have one glofish left (zebra danio) and he schools with my hatchetfish (a type of tetra). He actually hangs with them and keeps them moving around--it's really cute!

Hiya BB...I have a bunch of Tetras in my tropical tank. The only different Tetras that will school together in my Tetra tank are the Neons and the Cardinals. The others keep amongst themselves.

the 2nd school will most probably school with the first. I had 10neons and 10 green neons and they all schooled together. I think Neons and Cardinals would look awesome!

Tetras will group together only when they feel insecure however so if they are pretty comfortable in their environment, I would not expect too much that they'll swim around together. Neons and cardinals are almost similar and will still group together.
