I already have a Peppered Cory. Bought on the suggestion of a "PetSmart" professional as a good second fish in my Betta bowl. Didn't find out until I joined this forum that I am a big fat jerk for having only one Cory, in a 2 gallon bowl, with gravel. So as soon as I get the 55 gal up and running I will be stocking with several Peppered Corys. Meanwhile I have changed the substrate in the bowl to sand to keep him relatively happy until he can move, and a Cory friendly, plantable substrate will be used on the 55. Ive also got my eye out for a good deal on a 10-20 gal to transfer both the Betta and Cory to and retire the bowl tourtue chamber. My bad for trusting the PetSmart people to actually be "smart" about "pets", and for not doing any real research on my own. Lesson learned. This forum has been the best thing ever. I have learned so much in just a week since joining. Everyone is super helpful and friendly.i have got way more excited and serious about the hobby since joining.
Sorry for rambling. So, yes, Peppered Cory is the species I will be using. That is the base for me planning the rest of my tank.
