I was at my local petco and almost got some otocinclus as I can't find it in my other LFS...was surprised they had some...but as I looked closely...the 1inch otos all had like no tails...just the stub with no fins on the tail....Do you guys think it was the genetics of the stock? or something else happened? I didnt get it cause the other tanks all the fishes were on the bottom with ick!
