At what point should I consider adding cuttlebone to the tank? Curtis is now 3" by the way. Will it cause unsightly calcium deposits on the sides of the aquarium?
If it's time, should I break off a piece and just put it floating in the water or does it sink? Will he know what to do with it?
I think Curtis has a high prey drive because just leaving lettuce or veggies to float doesn't attract his attention. I have to hold it at the surface and make fluttering motions with it in order to get his attention. What should I do with the cuttlebone?????
