Ya I felt so bad.
I kept a couple (Bingo and Bongo, only 1 remains after Bongo was killed by my sister's over aggressive betta) with my goldfish along with a pregnant female. I scoured the tank for them and only came out with Bongo and Bingo. I assumed the female had died and been eaten. Low and behold I look over and there is a shrimp swimming at the top.
I was stupid enough to grab her out and put her in the shrimp tank, no acclimation. (the goldie tank is fully cycled but with high nitrates around 15. The shrimp tank has no reading on nitrite or nitrate and ammonia is under 1) I hope she makes it.
