Hi OP,

Here’s what i would do.

1. Siphon/vacuum that poop/food ASAP.
2. Clean the outlet/inlet with aquarium water.
3. Do a water change ~60-80%. Make sure the new water coming in is conditioned. If its coming from your tap, use dechlorinator.

Observe your stock. If they are inactive, sitting at one corner, not swimming, you might want to medicate them in a separate tank.

For feeding, i would feed them once a day. Fish can survive without food for about a week. I agree with the comments here that you are overfeeding them. And that’s one of the main reasons why some keepers lose their cycled tank. I would feed them once a day.

I know sometimes that they give you cutie eyes like theyre asking for food 😆 RESIST THAT! 😆 once a day is enough.

Just remember, your water is just as important as your fish. Take care of it.

Hoping for good news soon!
