Hello, so I've fired up a new planted tank. I have put 3 Zebra Danios in there on this past Saturday with an Otocinclus, and got a new blue dwarf gourami this last night. Prior to the new dwarf, the Danios schooled around the entire tank, everywhere. Now that I have put the dwarf in, the Danios school together at the top of the tank, favoring the current coming from the HOB Filter.
I do not believe this to be an oxygen issue as it literally started happening moments after the new gourami. The gourami has not touched or threated the Danios that I have seen.
So are the Danios just chickens? Has anyone else experienced this? Should they eventually return to the mid section or lower of the tank?
