Wow. Seems Ive gotten lucky then. Never had any problems with otocin being sensitive or not eating. These guys have been in this tank a little over 2 years? So far Ive counted 3 or 4 kids. I think the Yamato shrimp may have feasted on a few? Tank is heavily planted though. I just keep doing what Ive been doing. Can't afford any test kits right now though. For tank specs see my tank of the month entry.
