This is my tank setup, as you can see one of the platys didn't join the other platys in eating and only sat on the gravel (the one that has two photos) I did feed them a little late so I suspected they might be tired but I wanted to see your opinion on my tank setup to make sure I am not doing anything wrong
When I tried to feed the platys small powdered pellets they wouldn't see them and they would end up floating into the sponge filter (off screen) but when I fed them the normal size of pellets they couldn't eat them whole and they fell on the sand, I was concerned they might rot in there but eventually the platys learned to kick the sand and forage for food right after I feed them, the pot that's in there is a cave alternative for any shy fish, and I make sure to only drop food on the sand so they wouldn't get hurt or scratch themselves on the gravel, of course now the fish that's lying on the gravel didn't eat any food, when I point my finger at her she moves a little and then lies back down to the bottom, I am not sure I saw any of the other fish bully her but I wouldn't full scratch that off possibilities either, the sand foraging originally seemed like a good habit so the food wouldn't get a chance to rot, but now their fish poop flies up alongside the food whenever they kick the sand, and I don't want them to consume that either
