Practically my whole colony suddenly died
I just checked on my colony recently to feed them and found all aside from 2 (even 1 of them ended up passing) dead. The only one remaining is extremely lethargic and not doing well at all, it is an adult male. I'm very distraught to have found my colony like this. I noticed a strange smell in the tank too. I feed them freeze dried peas regularly and mist the tank regularly. The last time I checked on them they were all doing just fine, how could this have happened?!
