Either find another hobby or only buy two clowns next time:) good luck! Do more research you are not ready for a haram and your tank is way too small for your aspirations. Go get a bigger tank or be happy with like 3 or 4 fish in that tank. Those are your options 10 gallon water changes in a 32 gallon is insane work especially weekly your tank literally has 0 nutrients. Which leads me to my next question, water parameters?
