Nice comm tanks.. i do the same thing.. set one up and lose interest fairly quick... though since we set a tank up in our daughters room its been a dumping grounds for any neat lil' oddballs i find at the lfs. she enjoys the activity and color alot, and its nice haveing a tank that only get a few pellets and flakes for the most part and not a handfull of food each feeding lol.
btw the reticulated hillstream loaches are the best alage eaters ive ever owned! my one little guy keeps out 37 clean with the help of a few nerite snails.
