this is my first post on this forum so if i got this in the wrong place - i apologize. iv got 2 tire track eels; both are about 7" long right now. iv got them in a qt tank while i get my 55 gallon operational and ready for them. hopefully that will be within a few days from right now. iv read about how to keep them and know a little bit but i would like some expert insights. is pH truly important or are they readily adaptable? obviously they wolnt need their final aquarium for numerous years but when the time comes that they get enormous what size tank should i look for to keep them together in? or would that be a bad idea pairing them off like that in the same aquarium? should i opt for two 180 gallons?
