I got a little 3 gallon tall-ish tank to set up on my nightstand
I was wanting to put a freshwater fish in it,
but i dont know if that's too small for any freshwater fish?
I've never had one before, but I'm knowledgable with marine set-ups so i'm thinking it shouldn't be too difficult.
Is there a species you would recommend that wouldn't get too big and would be okay in a small set up?
Thanks!
