It's too small for one what, a clown fish? I have had the system going for over a month now. They have their own spots they take over in the tank. Like I said it's an 18 gallon system with an 8 gallon display. I did my research before I got into this lol
its not the water volume that they need, its the space. having rock in the display tank and sand takes up valuable space that they need. a month isn't very long to see if its working or not
