Deb, these by far have been the most challenging and the more enjoyable.
they came to me small dime sized.. to watch them grow and mature is a pleasure.. now as they mature the blue coloring on their backs show thu..very similar to the blue we see on our discus.
btw deb.. saw your discus.. makes me want to add more to my 75..down to 2 now over the years..these 2 have slowly picked the others out of the tank...
