Hi and welcome!

A little more info would be helpful, including a full stocking list and a picture of the tank. What is regular (weekly?) and how much water do you change (10%?, 50%?). What dechlorinator do you use for water changes and what do you feed them? I don't suppose you test parameters like pH, ammonia, nitrates? If yes those numbers would be helpful... If no, you can pick up a api freshwater test kit on Amazon. Not mandatory but certainly helpful good luck!
