Please help I have a 55 gal saltwater tank.I have a yellow tang and a niger triger and have no problems.Ever time I put snails in the tank they hook on to the side and look great.Within about 6 hours they will be laying on the bottom of the tank closed up.They will not open back up just lay there till they die.Have tested everything and it shows up fine.I do have a tan almost brown alige growing on the sand don't have a clue what it is or if that is what is killing the snails.
THANKS!
