I wish it was easy to feed mine :( They all have their own preferences and likes/dislikes, and amount they can eat without becoming bloated...
I feed small multiple meals throughout the day and I mix it up often..
My main food is homemade (shrimp, garlic, spinach mash), live food when I can get it, and then I round it all off with pellets (Omega One) every couple of days to give them any nutrition I may have missed. I don't use freeze dried as I rather not replace a healthy meal for one that is just empty calories.. and I don't use frozen as a lot of the times the freezing process removes a lot of nutrition as well.
But I have to cater to the ones that will only eat pellets, or won't touch live foods, etc which can be tricky and why I can't go on vacation and leave feeding up to other people.. I'd come home to some very po'd fish!
