midnight scare

so we have a 35 gallon fish tank with all kinds of fish. Tyler and I like getting crazy fish. We really wanted to get a crab or something crazy like that but they are super mean and can eat your other fish. One day when we were at the pet store we found a bamboo shrimp. The great thing about her is she is big enough so she wont get eaten by any of our other fish and she filter feeds so she eats whatever is in the water. We decided to name her Antoinette. On the top of our tank it is open. We use to have dojo loaches but unfortunately they committed suicide and jumped out of the tank. Well one morning at like 3 I came out into the living room to change and feed carter and i found Antoinette on the floor. I thought for sure she was a gonner. Especially after what had happened to our dojo loaches. I went to touch her and to my surprise she jumped at me scaring me half to death. I screamed and Tyler came out he thought something bad had happened. I tried to scope her up with a spoon but she kept jumping around. Tyler was finally able to scope her up and put her back into the tank. After that we were forced to take drastic measures and cover the open parts on the top of the tank. We also made it impossible to escape even where the food drops. there is no way we are having any more fish escape!
