It's beautiful fish in Flowerhorn world to me! Nice chubby mouth, fins are wide open, big kok (head), nice Pearly fella. Colors will be more solid once he settles down! Yes, can see some stress in the photo because he is at LFS. This guy will be stunning one day as he grows! If there are few dark spots above the main flower line, that one we call as double flowerline, can be seen in my profile pic.
Grade wise, healthier is the better, active and eat like a pig! If he falls in that category, you will enjoy that fish the most, because this fella are so interactive with their owners!
Start with clean water, proper temperature, great staple food and within few months, he might get double in the size. Most important in FH world is interaction, after feeding him, if you play for few minutes, he will have good stretching and will have great connection with you.
Please share some of the photos if you are getting him after he settled down! All the best and welcome to forum...
