Thanks, their diet consisted of New Life Spectrum 10mm pellets exclusively and lots of water changes.
The theory of supplementing fish vegetables, fruits, and other things in their diet is nonsense, when fed a high quality pellet there is no reason to supplement anything. Pablo Tepoot has nutritionist, biologist, and people way smarter than me on his staff helping to design their products so when some aquarist state they NEED this or that in their diet it's silly, everything they need is in NLS.
Here is great article from RD, many will recognize him from other forums like MFK but he's the most knowledgable person I've met on fish nutrition. Many people have asked me to write a article about aquatic nutrition but when there are things like this in place there really is no reason to.
