There is a step on the seamonkey instructions to make sure they have oxygen. Should I do this? The instructions say to dump the whole tank into another container. Then Pour them back. However, mine is seamonkeys on mars. It has little Oxygen wholes at the top. The Problem is water leaks out the wholes and gets all over and I lost 1 seamonkey and dont wanna loose anymore. They are stil little baby sea monkeys. Has anybody's seamonkeys died from not doing this? THANKS!
