Hi. I have 2 chinese hillstream loaches and 7 whits cloud mountain minnows. The minnows keep eating all the food for the loaches. I give them their flakes first on one side of tank and give the loaches their their sinking food on other side but the minnows see it on way down an eat them so obv don't wanna overfeed the minnow eithrr. I only feed when the loaches both out of hiding. Any other ideas to help them get some food?
