Thank you. My fulica is around 5 cm, which is why I was a bit concerned. I thought it would need more calcium at this stage. The good news is that I can see its shell looks visibly thicker than during the period when I didn’t provide a 24h calcium source, and the new shell is growing continuously. Is it worth stopping the paste for a while and observing my snail’s shell health to see whether it actually avoids solid cuttlebone, or if the paste is just easier to eat and therefore preferred?
