Exactly what does ash or phos. do for our fish? Is it a necessity in their diet?? I've been curious lately as I've been doing alot of nutritional research to find out what I can do to get the best out of my guys. and these are two properties I don't know much about. Do they need high amounts or should I look for low amounts in the foods I buy?
