I really love these little guys, and I'd love to stick 2 or 3 of these guys in my 29 gal. Problem is, my temperature is always about 72-78 degrees. I know they prefer about 65-75-ish, but would they do okay in that temperature range or should I just decide on something different...? And that being said, what would you recommend for a 29g in that temperature range? I'd like something that has a lot of personality and I'm fine if they hide often-- I'd like to make use of the "caves" in my tank.
