so every time I got to swamp bottom I have to play with the mantis shrimp. I love the thing.so my husband really wants one bad. so I am looking for a small non glass tank for sale. I am going to give in and get one. also does anyone know a way to lock the lid of a tank?? I would hate for my cat or my kid to mess with this shrimp. one more project know since my husband is all about saltwater tanks. I am taking my 30 long tank and setting it up for a zebra eel. Will this be big enough or should I go for a smaller eel. I like the snow flakes to.
