Hello, I didnt know which type of tetra to put this under but i would like some advice. I have never owned tetras but know some are peaceful and are schooling fish. If i get some for my 20 gallon with one molly and two platies, which type and how many should i get? they have some hiding places andit is planted.
Thanks

Would you like bigger or smaller tetras? If you want some small ones, I’d say neons, glowlights, or embers. But if you want some bigger ones you could do black skirts or something similar. Research some tetra species that you like and then post them here and we can tell you if thats a good fit and how many.

I like the serpae, black skirt, red eye, black phantom. But for the smaller ones i love the neon tetras but i heard they are hard to keep...

You could probably keep around 8 tetras of that size.
Of the bigger size? IT is a 20 gallon planted with 2 platies and a molly.. Also, am i right about neons being hard to keep?

Hello,
Thinking about buying neons but i have heard they are hard to keep. Before i buy them i would like some information on ways to keep them alive and opinions on if i should keep them or if i am wasting my time, money, and their lives
Thanks

Sometimes they really can be tricky, especially with the NTD going around.
I personally would never buy neons for my tanks, cardinal tetras would be my next pick.

I’m pretty sure 8 of the bigger ones should be fine, but start with 6. Neons are easy after a certain point. You just need to get a good stock from a trusted lfs and you’re good. But if the stock is questionable, they might be hard to acclimate.

Thank you!

Are cardinal tetras more hardy?

I believe, and they are warmer water fish.
My heater is set at 78. Thanks!

So

Threads have been merged as the two were overlapping with the same questions, it’s less confusing if all the information is in one place

That would be the top of the temperature range for the molly, but fine for the platties. It’s not exactly good for fish in long term to keep them at the top of their range, or the bottom in the cardinals case (if you were to keep it at 79)
Edit: I did a little more reading and some sites say 79, and some say 75 is minimum. So you could probably keep the temp at 79 and be fine.
