i am thinking of getting a fire eel for my new 180 gallon tank. it is 12 inches long and will be going in with 2 large oscars, two 8 inch jaguar cichlids, and 1 12 in pleco. There will be plenty of hiding places and lots of room for it to swim in. will it be alright or will i need to find a bigger one for sale? if i need to find a bigger one does anyone know where i can get it?
