I had a 20gallon long tank with a 6-7" O.S mantis shrimp for a couple months, i did a water change and the mantis died, i was depressed and left the tank as is, but turned off the filters and heater, now, a little over a month later, i was adding water to the tank and noticed little guys were wiggling and obviously dying, (half the water in the tank had evaporated and obviously the salt level had a sharp change... with further inspection i noticed they looked kinda likea mantis shrimp, i was wondering what you thought these things were??
PS i saw atleast 10 of these guys
