Thanx zbass,
Since posting this message I've read many accounts of people who were having the same problem. So I just try to take most of the hard objects out of the tank at feeding time. Althouth this does not stop my fimbriatus from hitting her snout on the glass itself, which I've seen her do more than once. It seems like every time her snout is almost completely healed, bam she does it again. I'm sure this can't be good over a long term period. I just don't know what else to do to prevent this.
Regards,
