is that right? I thought you said the mosquito fish were left untouched the last time. Didn't know they developed a taste for them...and you're sure its not a stork or small bird right? I had some small bird near my pond picking out the smaller fish one by one, daily, and pooping all over the rock it would perch on. In that case, you may have to wait a bit longer before putting them out there. Also when you put new fish out there, they will be in a bit of shockk and be easy target for the barbs to pick off. I mean, you could put the big barbs in a cage or tank temporarily, and let the smaller stuff grow and acclimate for a few weeks or months first., then let the big boys back in, they may have a better chance. Also, are the little tors bigger than the mosquito fish yet? At 3" that is not small either, and they have taller tougher bodies too...
