ok so i just found a crab--quite big actually about an 1.5in--in my tank (that is currently about to finish cycling) its dead, and i want to know whether i should take it out or just let it decompose in the tank...
Always take out dead critters if they're easily accessible. Otherwise you're just leaving in an imminent nutrient spike, particularly in the closed environment of a tank. Unless it's tiny and your tank is large...
