Hey Fish School fan! Here is a really impressive example of how wide a range of fish can be trained with the R2 Fish School training kit. Check out these videos of Tim Menai's fish named Siani swimming through the hoop. Siani is a shanny (also called a "common blenny", scientific name Lipophrys pholis).
If anyone else has videos of their fish doing tricks, please send them to me and I'll post about it.
