I apologize in advance for all of the back story here, but I think it's necessary for the decision making....
Ok so the stock in my 20g has been slowly decreasing due to the fact that it has my oldest fish in it, there doesn't seem to be anything wrong with the fish other than passing from old age. I am left with only 2 glolights, 6 neons, 1 female Betta, 3 otos, 3 amanos, 1 clown pleco and 2 female endlers who keep evading my net but should be in my guppy/endler breeding tank. I went to the fish store today to pick up some more fish and came home with 4 white clouds. Of course the plan was to put them in the 20g, but I've been thinking maybe they would fit better in my 30g.
The original plan for my 30g was to have a tank of all small fish to make it look bigger and so that I could have more fish
However, I ended up with 6 zebra danios in the tank, they seem to really enjoy the length of the 30g, but they're so active they're sort of terrorizing the smaller fish so I'm wondering if they should be put back in the 20g tank where the other fish weren't as bothered by their activity and put the white clouds in the 30g.
So the question is:
Should I leave the zebra danios in the 30g and put the white clouds in the 20g
move the zebras back to the 20g and put the white clouds into the 30?
Any input would be more than welcome!
and sorry for the super long post to ask such a simple question!
