Thanks Gena. I put some peeled frozen peas in there last night and the giant apple snail(he is yellow colored) went to town on them. The 2 little ones(they are only about the size of a large marble) didnt even notice it. Maybe I will put some lettuce in there tonight. Where do you buy powdered calcium? The LFS? What kind of babyfood do you use? Veggies? Fruit? And will all this calcium cause any problems for my betta?
