Heard that from others as well. I lost my first clutch of babies in an aquarium and had a veiled at the shop I worked at that was suffering until we moved it. Could just be coincidence... Could be something I did.NickTide said..."One thing that seems to be a drawback to veildes is in MY experience (personal and pet shop), they don't take glass cages as well" ...funny but I've kept mine in exo Terra glass cages for years and they do great.
