Its a nice eel, but this eel demands a larger tank then that of a 35 gal tank
This is if feed healthy foods is to be one of the most active eels that not will grow to large other then its normal max growth. This eel demands a tank as large as a 75 and 90 would be better with much LR and water currents. Also because in how often you must feed this eel and how much waste it will produce, you would need to do large weekly water changes. If you not figured this out already, you will not be able to manage to keep other fish with this eel, other then damsels that would help you to eat any smaller uneaten foods and would also become food as well themselves. This eel will grow fast to your amaze and not try to offer it less foods for then you will have an unhealthy species instead and will not be as active as it should be. FW Mollies as food?!! Bad choice for the foods you offer this eel must be from the ocean waters and when you buy at the store, stay away from farm raised products and try to only buy from a fresh sea food market and buy as well for it octopus and squid as well as fish. So know this, before long this 35 gal tank will be already too small a tank for this eel, I hope the LFS your bought the eel from has told you of this!
