Upgrade 20L to 29? Pros and Cons.

[AllFishNoBrakes]

@EricksonAquatics I would say more top/mid, but they were also in a 20 long, which is hard to separate the levels. That being said, I never saw them on the bottom of the tank. 
 

I took them out of the 20 long, and put them in a 10 gallon qt/holding tank, and again never saw them at a bottom. 
 

When I get home from vacation, I’m going to put them in a 10 gallon that I converted to blackwater with Pygmy Cory’s and an ADF. I expect them to hang out top and mid where the Cory’s hang out bottom and mid.
