lei + silver = no go first time around. my lei went postal on it and beat the crap out of it =\ i was hoping he'd take nicely to it but nope. less then 12 hours and the silver was missing a ton of scales. i moved the silver to my 60gal and im gonna let it heal and get a lil bigger then try again. it was worth a shot tho because it looked cool as heck with them together. so yah ill try it again later. might put up a divider so they see eachother in the same tank but can't attack eachother, then maybe try removing it every now n then til they get used to eachother.
