some time ago I bought three Firemouths and two Salvini. one of each have failed to grow or even seem happy in the tank, they eat, but their colors are weak and they never grow. the Firemouth eventually either died or was murdered, and now I worry the same fate awaits the Salvini. does anyone have any explanation as to why certain fish simply fail to thrive?
there was no evidence of bullying with the Firemouth, and none now with the Salvini, but the proof is there in the photos, the female is three times the size of the male and full of color, and they were the same size when I bought them.
