Hi, I just purchased a 500 gallon salt water tank with two eels- a morey eel and a snowflake moray eel, a sergeant major fish and I'm not sure what he other one is (same size). We like salt water tanks and its giving my seven year old son the opportunity to learn. (as well as myself) Our family consists of an African Grey Parriot (Gracie) two turtles, two frogs, a dog (UNO) and a cat (Pooh). We are confident the animals will survive but would like to learn as much as we can to make them comfortable. We have had the tank for about three weeks and are having a little diifficulty getting the eels to eat. Any advice you could offer would be greatly appreciated.
