Just wondering if anyone has kept Tigrinus with red hook silver dollars (or any SD's for that matter). I've got to move some fish around, and don't want the SD's muching on the streamers or whiskers of any of my tigs.
My widebar silver dollar nipped off half of my arowana's barbel today. It happened so fast. There's always a possibility that your red hooks can munch your tigs whiskers.
The SD's are all at least 3", probably closer to 3.5" with the largest being 5". I'm not worried about the Tigs eating the SD's because it would be quite a stretch, just the SD's nipping the whiskers and tail filaments of my tigs.
Fast fish sleep too, and that's when most seem to get eaten by catfish IME.
