This is a thing I wonder about a lot.. how often to add veg?
I feed wafers and catfish pellets but my barbs are hungry greedy little ******s and do not let many if any sink to the bottom.
They also attack any veg for a good while before they lose interest, if I try say mushroom then for some reason my Fire Parrot fish stands guard over it while 2 of my catfish try their best to get a nibble, its rather funny to watch. He does not bother the plecs when they eat it, its like he has been hired as their food minder.
Any back to the point.. how often for veg ?
