years ago, with my very first tank, a very overstocked 10G, I tried to introduce a lone cory paleatus in the tank. The tank had, among many others, a school of 6 tiger barbs. Checked on the tank before going to bed to find poor Cory hiding in a corner- finless and bleeding:-O . He did'nt make it through the night despite gallant efforts and pints of stress coat. I've never tried keeping Cories with barbs again, even though I love them in a community tank-little sniffing puppy dog fish! Anyway the guys at the LFS could hardly believe it. Any feedback???
