My daughter use to have a 29 fresh in her room. Oops! It has migrated to my office and has live rock and plants and a goby. Now she has a little 15 gallon that has a few freshies. I thought that I was going to convert it to a salt mini but the darn fish WON"T DIE! I forget to feed them for a week at a time, Never change water, and they are currently having little bitty babies, AND NOONE IS EATING THE BABIES! Don't fish always eat little baby fish? It has a big pleco that needs a much larger home, a betta, 4 platies (I think), baby platies and 1 rouge guppy. Maybe a few albino cories (ugly little monsters). All those fish shoved into that little tank and they are still alive.
