Not unacceptable at all! I was just saying I didn't recommend it because it's not the ideal
It's just advice really and I'm only speaking from my one experience. I used to keep 3 cories in a 10g, then moved them to a 30g where there are 12 and I see such a difference in them! They weren't unhappy before by any stretch of the imagination, but now they are really happy, and have started to breed.
