I introduced my cbb about 43 days ago to my 75 gal and he eats PE mysis aggressively. He eats off the water column since the day I got him so I had virtually zero trouble keeping him. He sometimes eats little chunks of rods food but mostly only eats PE mysis. He sometimes paces up and down on the glass which has me a little concerned but when he’s not, he looks for food and pecks on the rock. I’m managing ich right now by adding vitamins and fats in his food and also feeding heavier.
