Agreed. This tank looks pretty small to house a sailfin. He may be ok right now, but will quickly outgrow anything smaller than a 125. More rock is going to be a must to keep up with the high bioload in your tank right now. As a general rule of thumb you should have at least 1lbs of rock per gallon of water. I would also say that you are going to need more snails and hermit crabs to act as your "cleanup crew".

What type of lighting and filtration do you have? This will help us determine what types of fish and invert you can keep.
