Ive decided to get a hospital / fry tank would it be ok to mix the 2 obviously not at the same time of course but use the tank to treat a sick fish and use it to hold fry. Does it need to have anything in it like substrate or just keep it bare with just a filter and a heater. I was going to keep it going with 2 mollies in it so it will stayed cycled how does this sound??
