Lemon Tetras and Rosey Red Minnows

[ZeroLivesLeft]

Alright so I know this is a weird and maybe a dumb question but i was wondering if you can keep Rosey Minnows with Lemon Tetras?

I know that Minnows aren't tropical like Tetras so idk if that is a big problem or not?

I'm also worried about the Minnows being sick and getting my Tetras sick. What can i look for to know if they are sick or not.

Lastly should I worry about the Minnows eating or biting my tetras? or vice versa? or will it not be a problem at all?

My girlfriend bought them as feeder fish for her salamanders but theyre still young and couldnt eat them yet. the ones she would be giving me havent been fed to anything yet. I always here feeders are bad to keep as pets but thats why I want to check if they are sick. I only have the Tetras in a 29 gallon tank at the moment so really it is kind of spacey.

Thanks
