my mob like lettuce ( stuff with darkish leaves like romaine) but it took a few attempts at putting it in the tank before they realized it was FOOD & now my barbs & red eye tetras love it - not to mention my algae eater who scoffs it v quickly. i blanche it first(pour boiling water over it for a few mins) & then peg it down somewhere with a rock. you need to take the leftovers out after a couple of days or you get disintegrated lettuce bits floating everywhere.
