The panduro are a little over one inch long and they were terrorizing 10 small Koi Angels, 14 small Panda Cory`s and two full grown Dicrossus maculatus. Finally had to take out the Panduro and put them in there own tank George Hi everyone, I've had a trio of panduro (one male and two spawning females) take over the entire bottom few inches of a heavily planted 90-gallon tank with lots of caves. They dominated a pair of Nanochromis transvestitus and forced all the Corys to stay in the corner all day long. A. panduro seem to be mighty tough cookies. Keith Kurko
