I feed my fish once a day ,what they can eat in 4-5 minutes. Just got 6 cories yesterday and dropped in 2 hikari wafers for them ,problem is once the other fish were done eating there flakes they rushed down to the wafers and stole them from the cories. Will I have to feed these guys at night? Is that ok because these guys are so passive and just let the other fish take over. Even my cherry barbs are their food and they dont even eat much. I have 3 platies,4 mollies ,6 cherry barbs ,5 bloodfin tetras and 5 zebra danios. The barbs ,platies and mollies were really being bullies. Do any of you guys have this problem? BTW seems as if most of the fish are fighting over the wafers. Looks like a huge problem
