Hey so I'm going to start up a 20 gallon tank. I have about a month to do research(I'm going for a week vacation at the end of this month).
I want to include neon tetras in my tank. I also have found a strong liking towards black neon tetras. I was wondering if they'd school together?
Generally speaking the black neons and normal neon tetras will not exclusively shoal together, they may intermingle from time to time; but more often than not they will simply stick with their conspecifics.
In a 20 gallon, preferably a 20 gallon Long you could have two nice shoals of 6 neons and 6 blacks, granted further stocking would be a bit limited. I think it could look pretty nice.
