As long as your tank is cycled and the water parameters are all good it should be fine murky water shouldnt bother your axie but if it is soo cloudy you cant see anything you might wanna hold out a little as u said it might be missions feeding and cleaning up waste. Has your axie got a suitable home at the moment while you are getting this tank sorted? If he's happy where he is it might be worth riding it out another 2/3days to see if the cloudyness improves!
Someone may correct me on the cloudy water and axie thing but as far as im aware theyre natural habitat is pretty dark and murky and mine diddnt have a problem with the sandy cloudy water but then again if you cant even see into it to feed the little monster your water is alot more cloudy than mine ever was, so its probably best to wait for more feedback before u put him in there!
Bet you cant wait to get ur axie into his new home! I wanna get mine a nice huge new tank but money is soo tight at the moment and mine is plenty big enough at the mo just cant stop spoiling him rotten! gonna go get him some more munchies in abit, nice juicy crickets mmmmm!
