I bought this little guy like 3 weeks ago.He has potential and showing good progress.I feed him grand sumo,chingmix headbooster,nls,dainchi,osi spirulina etc.Here some photos of him , hope you like it.
I did not have good experience with CM either, it caused my FH to have gray poop and he wasn't a huge fan of it. At approx 6.5-7" currently he's eating 4.5mm NLS floating pellets.
