hey guys earlier this week I purchased 2 mystery snail on the small side there doing great my tanks already much cleaner but since the purchase I noticed these white bits on the tip of there shell I did my research and found out they need
calcium for perfect shell quality and you give it to them through calcium drops or what ever you put into the tank water. But for reasons that would take to long to explain I can not get them so I was wondering is there any other way like for example a vegitable which is high in calcium and if its a kind of food that im ment to purchase from shops I also cant because I made a deal with my mum that I would not purchase anything else extra for them until my skool finish and the last thing i was aloud to get was livefood which my fish needed so I cant pass over that line.
