I’m new to this hobby. I ended up with a bamboo shrimp in my heavily planted 10 gallon tank due to ignorance. A lady at an aquarium told me they were scavengers, last time I ever get an animal without doing research first. Anyway, she was doing really well, and I had her a month, she was fanning most of the time, I was spot feeding her fry powder and algae. I started out with blue gravel from Walmart and ended up hating it because I wanted it to look natural and planted. I ended up changing out the substrate to sand, I figured it would be ok since I’m spot feeding anyway and I kept all the filter media. After that she wasn't fanning as much but she was still fanning a bit. She was walking around the tank more. On a whim this same lady says dwarf Mexican crayfish are great scavengers and are peaceful and won’t bother fish or shrimp. I wanted something to pick up the left over food the shrimp was missing to prevent from polluting my tank. The day I introduced them, it must of scared the bamboo, she was running around the tank as fast as I’ve ever seen. The next day, I catch the Mexican dwarf crayfish attached to my Bettas fins so I return them. My Bamboo girl doesn’t fan or move all day. I have a lid on my tank but there is a small opening, well this morning we see her on the kitchen floor, she got out and went a pretty far distance. I’m surprised she even survived the fall from the tank stand down. I feel terrible, she must of been freaked out by the visitors? Anyway, I’m pretty sure she’s dead, but she did move when I picked her up, it looked like a reflex reaction. I have her in the tank now, it’s been an hour and she’s just floating there dead. I don’t want to take her out if she’s still alive, but I also don’t want her to be dead and cause an ammonia spike, what should I do? How long can they be out of the water? If she moved is that a reflex or could she be alive? I’d think if she was alive she’d be grabbing onto something and hiding.
