I notice some kind of fuzz or something on the skeleton? Have you tested your product water with an ammonia test kit maybe chloramines are the culprit?I wish then I could take them out and put them in the “dungeon” lol but I took numerous time lapse videos over the past few days hoping it was my cleaner shrimp, hermit crabs or maybe one of the fish but nothing. That’s how I usually find eaters lol
But yeah my ALK is on point with the trident controlled dosing.
