We have a 35l tank which I was planning on getting a betta for. However I've just been to my local Maidenhead Aquatics and have been told that a Betta won't be happy on its own and I should get some tetras or another type of small shoaling fish to go with it.
I then asked whether this would be overstocking a 35l to be told no it would still be under stocked.
This conversation has left me doubting myself and I left without any fish as I wanted come away and do more research.
Does anyone have any advice?
