I've never had cleaner shrimps molt that often. On average, my pair will molt about once a month. 2-3 days sounds like an aweful lot and I have no idea why yours is molting so often.
hmmm.. not sure myself cause I am new to reef keeping and just had the tank for around 3months... but I do noticed the smallest Cleaner grown 1cm since I got him/her
I just left it in the tank.. the spagetti worm and my fish chew on it all the time on the empty shell... Maybe not 2-3 day.. I think each one molt around a week time. 2 Shrimps there so I get confused sometime but do find a empty shell from the molting almost each week
Haven't dose iodine for like over a month.. I only dose it when I don't have time to do water change. Only problem is my Shrimps eat lot stealing and fighting foods from my clown and Porcupine puffer.
