wow thx for the info, i guess mine wasn't that clean, i think there all have RI at early stage maybe??

they all have this small bubble at sides lips, although there was no wheezing, clicking nor popping sound during breathing, and some are eating just fine.


if i'm keeping all my BP in a rack system with heat tape with thermostat set at 33C

with ambient 28-31C (at summer it could get 33C), do you think such high temp could cause the RI, but i'm keeping all my BP for about 2 years now, some from 100gr until now 1,4 kg with no serious problem, should i get Air Conditioner?
