The father was pure red dragon while the mother was half red dragon and half fader. So I just guestimated the percentages for the 2 daughters.Few fish do that. I think JSpilo s fish doesn't eat sinking pellets too and I talked with someone who's fish didn't eat floating pellets. I guess if they are fed one type for their life they will get accustomed to it.
How come 2/3rd red dragon? That's a hard number to get.
