I must got 2 new albino polypterus palmas, they're almost 3'', from what I hear the best thing to help them grow is heat at 78 or so and beefheart and blood worms, i tried feeding them chopped up silversides but no dice, didn't eat any. they're in a 10 gallon with a few guppies i'm hoping will slowly dissappear.... any other suggestions?
