Hey guys, I'm new here so sorry if this is a dumb question. I've had my male betta (Beefy) for around 6 months now in a ~1.5 gallon tank and he's been doing very well, healthy as ever. I went to Petsmart and the woman in the fish department said that even though it was a small tank, since i had some moss in the bottom it would be fine and even beneficial to add ghost shrimp to the tank. Yesterday I added them, after I changed the water. Beefy didn't seem threatened, he swam near them but otherwise never flared or paid them much attention. The water in the tank is roughly 75 degrees Fahrenheit, which from what I have read is healthy for the shrimp. I woke up this morning, and the two shrimp were close together and not moving, though I saw no injuries or damage. Basically what I'm asking is...were they dead or sleeping/something else?
