Submersible heater exploded -- what killed my shrimp?
I had a Stealth submersible heater explode in my tank sometime after the lights were out for the night. It blew the dial & top right off the unit. I have never had this happen before. I suppose the heater was a couple of years old, but had been holding the temps just fine, which is what I liked about these heaters. Dependable.
The temperature was 86 F when I discovered it in the morning. The fish were fine (but hiding, so maybe 'FINE' is not the correct term), the the snails were fine, but the shrimp were all dead. Amano & RCS. There was one small wood shrimp that survived, but it didn't look particularly good until I moved it to another tank.
This is an EXTREMELY heavily planted tank with about 1/3 of the space volume consumed with mosses, so there are a LOT of little dead shrimp. I am watching and treating for an ammonia spike per the dead critters.
Could there be copper or some other elements that were exposed when the unit exploded that killed the shrimp? Why not the snails?
