well thank you all for the input it is so much appreciated and i have news....it was my lovley Oscar Albie (1 year old 12inch long)who broke the thermometer and yes i am buying the kind that goes on the outside of the tank....and after her spaz out yesterday morning i am now convinced that it was indeed her(my oscar) who hurt my Jack probably by smacking him with her fins or slamming into him during her frenzy .....Jack has a designated area behind this large rock that is just big enough for him to turn around in and i think she caught him behind it .....next question....do we think he will be ok...because i have noticed since he doesn't get around so well he has rubbed the scales off of a portion of his bellie...good news is other then that he is not going down hill so to speak...but i am now concerned with the scale situation and it causeing an infection or something nasty (ich )from stress starting.....i have never had problems with any of my tanks before...and don't want them now...new advice always welcome....i have other tanks a
and empty 10 gallon
a 55 gal with (2 angels, 2 balas, and four male platies)
a 55 gal with( a red oscar and one convict)
my 135 that jack is in houses 1 Oscar, 4 convicts, and 1 red tail shark
now i have seen comments about size of convicts all of mine are from mouth to fin 8-9inches long two of them have beautiful caps
