Agree with the previous comments about overfeeding (something I am terrible for!) Snails and brisslenoses are also great for keeping the tank clear for longer.

Have you checked the ph ammonia and nitrate levels in your tank? if it’s not food related it could be an imbalance of something ? Does it have a filter system? If so Are you changing out filters monthly?

Overfeeding, resulting in lots of leftover food in the water, can cause cloudiness. Overfeeding also leads to lots of poo…..more cloudiness

Check up on the kids they are probably overfeeding the fish or possible dropping something into the water

Yep, I agree with comment already made. Over feeding can cause cloudiness

Make sure you’re not overfeeding your fish – uneaten food often causes cloudiness.
