i don't really see that big of a problem doing a star only tank. i started my 30gal in that direction, but right now its a qt until my 75gal is complete and cycled. I still may keep with it and go with a star only tank, time will tell.
like stated, i think your tank is a little to small, i'd go no smaller than 10 or 15 gallons. but you must keep the parameters in check.
i find brittles/serpents more fun to watch, thats just me.
