After reading the many great ideas on here, thought I would share one of mine. I bought a blue cup betta (who also turned out to be a tail-biter) on impulse. I knew about a lot of the basics and had my old setup on hand. He's in a 2.5 gal with heater, hood, and two plants. I wanted a tunnel or cave but he hated the coffee cup, and the coconut (both of them) and the ship I had...so I went in search of hamster tubes and came across these puzzle playgrounds for hamsters...they click together and have multiple options for size and shape. So he got a house and a triangle tunnel and loves them. I just popped out random pieces so I can swim through wherever. And they are perforated so I plan on just covering them with moss to make them squishy! Glad I finally found something that makes us both happy. I've been reading this and other sites for weeks and can't wait to upgrade to planted tanks and the like. It'll be a little while though. Thanks for all the great advice.
