Ok just finishing off this thread with one final update. I finished the last dose of the prazi pro treatment a while ago and while my JD has maintained his healthy and aggressive demeanor, he continues to intentionally bash his head and gill areas against the drift wood and such in the aquarium. His appetite for things like earthworms, mysis shrimp, and blood worms has returned to 100% normal, however he still refuses to touch any flakes or pellets of any kind. I suppose I'm happy in that he's eating and colorful and feisty, he continues to boss my little female true festae around. My next big purchase for my aquariums is going to be this month, I'll be switching over from tap water to using RO filtered water. I'm excited about it, a little overwhelmed about getting things transferred over smoothly, and excited to see if maybe this helps alleviate some of my JD's odd behaviors even more? Anyways, thanks for the interests and advice throughout everyone!
