To Add to the note about your lion not eating him when I dropped mine in there my lion had no care for him, they also hide alot. I was wrong about the 3" as I said before. I have not really looked at him for some time and he has seen to grow to about id say about 4-5" or so. He takes the silversides just as easy as the lion I put them right in front of him and in the blink of an eye they are gone!
Just curious but what if I mixed the remaining 60 g of salt when I get the tank today and just add it in. Will that work? Will that be ok? That way the tank will be up and running today with the fish in it.
