I just started using Repashy calcium plus yesterday .. Because of a man names Jason up above. my pet store is stupid and gave me the wrong kind so they have onlybeen getting calcium and no vitamins . but yesterday they at least got one with the supplement . mine dont go all crazy for them so by the time they eat one its fell in the water and washed most the supplement of which annoys me to the fullest.. Today is tank cleaning day and I will move the bar up a little more on my thermometer to see if I can get it to 75 thats where I myself would like it to be .. and yes mine bark all the time doesnt matter them temp they go back and forth with each other . Then one will hop on one and they will make that other noise like get off me its so fun to hear!
