I am going to also start breeding cory cats for sale to the local fish stores.  My blue rams are in demand and doing well.  The stores aren't having troubles with them, like they have with ones they ordered.  My acclimation to full tap water from half R/O, half tap seems to be working as there are very minimal losses in my tanks or at the stores.  Anyway, I want to add the cory cats as they are another high demand fish and I can raise the fry in the same tanks as the ram fry and they will help eat up any food the baby rams miss.  This of course means adding more tanks to hold the breeding adults, which means more water changes, but all well. 

For cory species, I think I am going to use albino corydoras aeneus, corydoras paleatus, and corydoras panda.  These seem to be the most popular types around here.  If I ever find dwarf corys I will probably try them as well (corydoras hasbrosus or corydoras pygmaeus), just because I like them.  I will set up three 15 gallon tanks to house the breeding groups and keep them similar to my breeding groups of blue rams.  My only dilema here is that they adhere their eggs to surfaces, including the glass of the tank.  Trying to get the eggs off of the glass would be a bit hard to do without damaging them.  Any ideas?
