I have a 1.5 gallon tank. It's occupied by a small 8W heater to keep it around 80*F, and a standard crown tail. At the moment my arsenal of toys consists of two 8" fake plants and Squidward's house.
The problem is, Squidward's house takes up a lot of space, and I'm worried that the amount of displacement it causes isn't worth the extra leg room. Because the tank is so small, should I sacrifice the hiding spot for more swim space? Downsize the cave? He's pretty active and I've never seen him chill inside of it for prolonged periods of time, but for all I know he might love it.
The other plant is a nice leafy silk plant; takes up about as much room as the green one in there at the moment.
