Can anyone identify the fish I saw at the local lfs. No one at the store knew what they were. the fish came in with the common pl*co's, it has nearly the same coloration and shape as the common pl*co but is flatter and has barbels under it's face area. this fish also is a very fast swimmer and burrows under the gravel almost completely, I think it may be some type of catfish not sure. any help greatly appreciated, may go back after them if I can get them identified and they would do well with my other fish. also they were real cheap for a fish in this area less than $3.
