I visited PetCo recently “just looking” and found some incredible blue snails. I already had six, but these were different They were a soft pale opaque blue with no hint of green. Just perfectly sky blue. I took four home. After about a week I noticed the shell growing out did not appear to be the same colour. Then part of the top shell layer came off on two of the snails. The shell underneath is quite dark.
Does anyone have any idea what was done to the shells of these snails? I am afraid whatever they were treated with has done serious damage to their shells.
Thanks,
Di
