I know there hasn't been a single day they haven't eaten anything, and they always pounce on it hard as usual, but the chewing and spitting is wierd cuz sometimes they get it down, and sometimes they move on to the next piece. I would have chalked it up to a bad bag if they didn't also leave a couple pieces of smelt a couple times, and a bunch of pellets one day. I did a 50% change work gravel clean about a week ago and issue wasn't much different. Cleaned and rinsed everything, replace mechanical twice as fast. And for example yesterday they only left 1-2 pieces of smelt which was gone in the morning, day before that they ate 100% of their pellets. Day before that about 80% of shrimp, today maybe 40-50% of it. They're not skinny by any means, still really active and spots really white, since the issue started though I have reduced their food by 20%. I know if I change brand of shrimp sometimes they refuse it, but i didnt this time. In fact I had to buy tail on shrimp when this issue started and they didn't eat it so I just thought it was because of that because they tend not to like the tail on shrimp. Male trying to breed the small female gotta be a sign that they are somewhat happy right? Temp is also steady at 26.6.
I also dosed with prazi about 6 months ago, I do it yearly. I haven't had had uv in 4 months or so because I got it shipped broken 3 times, first time the 5 foot bulb was shipped in a 2.5 foot box, true story.
