I'll share some update pics after taking a few this weekend. Last week was my first time traveling (I travel once a month, week at a time for work) and being away. I've done this countless times with discus, for up to 20 days, but usually it's about 7-10 days. I feed heavier two weeks leading up, increase water changes the week of leaving, and do one really large water change the day before leaving. I also add a few bags of purigen as insurance.
I was gone 7 days this time, and when I came back the flowerhorn was doing just fine. Active, full bodied, etc. As expected, he lost some color, which came back in a day. I actually tried feeding him NLS pellets again given the 7 day starvation.. I cannot believe that he just spit them right back out lol. You would think that he'd eat just about anything after 7 days of not eating. He really is just insanely picky smh.
I did order some gamma vegetarian frozen food.. I'm hoping that he takes to it since it's frozen but we'll see. Gotta figure out a way to get more plant matter/veggies in for him. Right now the only source is spirulina, which is combined with the frozen shrimp.
