Need Experienced Persons Help!

Those are not generic names Jenny. They are species names and you are right about all 3 looking very different. The habrosus look like tiny versions of a paleatus but the other two have very different looks. This is the 3 we are talking about.

Ah got you :D

In that case it is just the C pygmaeus I've had experiences with but they proved to be a good addition to a couple of my tanks. They're all great little fish though (I'll have to check back on your photos when I get home) :D
 
No need to check out my pictures Jenny, they match well with the pictures taken by other keepers of these pygmy cories. I especially like my habrosus in tanks with other fish. They tend to try to blend in and match the actions of fish like endlers. The hastatus have proven to be the most hardy in my hard water though. My habrosus are only lasting about a year in my tanks while the hastatus are well into their second year in my tanks and still thriving.
 
I was just surprised by how good the hastatus look in that picture! Sounds like they might have better longevity (although we know your water is pretty hard) in addition to the good looks. On the other hand, isn't it the habrosus that stay more bottom level than the other two types? Also, another question: One of the positives cited for pygmy cories in general is that they get lively and fun in a large group. Anyone have enough experience with large groups of more than one type to say which are more lively or if all of them are? ...that sort of description.

The hastatus that you see swimming in a group of 4 is part of a stocking of 13 that I have in a 20 gallon tank. Until I added in another species of cory to embolden them, I never saw them after the first week but sometimes surprised them when I walked into the room. They were beyond shy until they had some larger friends to make them feel safe. The habrosus in my endlers tanks swim around as if they were part of the endlers, absolutely fearlessly. I only have groups of 5 or 6 in each tank but it doesn't seem to bother them. The pygmaeus are in a group of 10 which I never seem to see more than 1 or 2 at a time out in the open. Each species is very active when they are out in the open, but only the habrosus seem to make a habit of being easy to find in the tank.
