Which shools the most: Cardinal, Neon, Black Neon or Harlequin Rasbora?
I want a schooling fish that will school closely together. Not scattered. I have a 90 gallon that heavily planted.
Which one, out of these, schools the most and closely always? Cardinal tetras, neon tetras, black neon tetras, or harlequin rasboras? which ever one I choose, I'll buy 8 - 12 of them.
I've had 6 neons before but i remember they tend to scatter off a bit. I want one that will always school together and very closely. This is cause i think it looks better and looks more cool.
If you can think of other types that shools closely together, please tell me.
other fish in the 90 g include tiger barbs, blue gouramis, siamese algae eaters, bristlenose pleco, oto cat, kuhli loach and 1 redtail shark.
