Yeah 0 for trite and ammonia. Nitrate is 15ppm.
I don't see the lap eating and the amount of food leftover in the morning leads me to believe he isn't eating much at all. My endli is a pig though, so are laps just generally not as big of eaters and/or slower growers?
Idk man lots of variables. I wouldnt say laps are slow growers. Any signs of bullying ? Torn fins ?
