I've noticed that most of my fish have no place to hide. My rainbow shark lives in a cave and the rest just swim around. In my tank I have 3 caves, and one of them has plastic plants coming out of it. I also have several short (1.5") spiny plastic plants and about a 4" tall plastic plant. What other things do i need to make my fish feel more secure? Do my dif. kinds of fish need anything in particular? I'd appreciate any ideas.
