I have a 10 gallon tank with artificial plants, a castle, some rock and some castle ruins with lots of place to hide and go in and out of. I put my betta in there from a 2 gallon unheated, unfiltered container. The 10 gallon has a heater and a filter. Today I put in 3 pepper corys. I am a little confused though because they were tagged pepper cory in the store and when I went online to read up a little more on them there are "peppered" corys and "salt and pepper" corys the latter is a Habrosas cory and grows to 1" the peppered is a paleatus cory and grows to 2.5" how can I be certain which one I have. If I have the larger variety Is my tank now fully stocked or can I put anything else in there. If they are the smaller variety, same question, can I put anything else in there and if so what would you suggest. By the way the betta I have is a sweet boy and has not shown any aggression what so ever. In fact since the corys went in he has been hoovering the bottom of the tank like they do. I guess he must be wondering what's so interesting down there.
