In my experience, this fish doesn't seem to jump out after it gets accustomed to its new home. I've have one now that does great. Eats everything, especially frozen mysis. I had one before this one that was very "social". he came out and greeted me whenever it was time to feed. Unfortunatley he jumped out while I was in school because the power had gone out. I had a very loose top on my tank from my stupid Emperor filter that built into the canopie. Make sure you have a lid on the tank. other than that they are one of the easiest fish i've ever kept. easier than my seahorse lol:
