Things were going swimmingly well...
But my wife decided it was time for the 2 SAE in the 29g to "go", so after a real pain of chasing them down, I got them moved to the 55.
Within 24 hours, the school of Rummynose were hiding out in the thick water sprite. Yesterday afternoon, a harlequin Rasbora was actin crazy, then died.
This afternoon, I got a text from the wife- a rummynose and a Cory were dead. A couple of hours later, another rummynose.
No sign of illness, water parameters are great- I'm at a loss. Yet after discussion with wife, we have concluded that the SAE are to blame- both for these deaths, and the death of her previous angelfish (in 29g).
The SAE are nearly always super-hyperactive. They chase each other all over, then chase everyone else (except my angelfish). I look at them as terrorists. They don't seem to be trying to eat anyone else, not do they seem to be even actually biting other fish. Just chasing and being hyper, stressing the tankmates.
