What a cool looking fish! I just met an elephant nose today at an lfs. I've been doing some research, and I believe, and would like to, offer this fish a home. The ethics of buying fish that are caught in the wild has been bugging me lately, but have read that these fish are now being bred in captivity. I realize that feeding must occur after dark in order for them to survive. The lfs has reccomended frozen blood worms. My only huge concern is substrate. I have a gravel bottom in my aquarium. Could I have a mixed bottom? Can I set up an area in part of the aquarium with a finner gravel, put in a "hollow log" so he can have a home patch to play in as he chooses?
