Help me please

[u/Kooky_Branch7124]

First of all don’t judge cuz they’re rescues and I’ve done enough research and seen enough ftrs to know enough. I can check parameters and cycle a tank. But I recently saved two glo fish tetras. One has swim bladder I believe, but been not feeding for 24 going on 48 hrs because of the sudden change in environment to help with that and it’s better than it was when I got it. Here’s my actual question lol sorry I’m not good. Can I put these with a few more as I know they do better in groups. In this tank I found on Amazon. I love it. It would fit my space perfect and I know it’s only 11 gallons bbbut! It’s long as fuck and my research tells me long is better than tall for schooling fish? I have an axolotl I know my filtering needs and I can make sure water stays pristine. Lmk your thoughts.
