Well thankfully they now know me as the one-who-brings-food so they hang around in the hairgrass at the front of their tank waiting for me to feed them.
The dominant male chases the other fish off on occasion, but aside from a few nips there's no missing scales or torn fins. They have no problems thronging around for food, and I use tweezers to make sure the tiniest male gets fed too - he's about the size of a large tetra. The peat and IAL have brought the pH down and darkened up the water, and there are lots of places to hide in amongst the water lettuce roots. I'm actually surprised by how well they get along considering they are in about a 4 gallons of water because I didn't want them jumping.
I really like the wilds, and since I have finally assembled my large fish tank stand, I intend on picking up a pair of Uberis and Rutilan, as well as a small group of Unimacs to fill my 46 gallon. I am going to snap some photos of my set-up and hopefully also of my Coccinas later on today.
