Just to give you the "big" picture... Fear not! I know I'm overstocked, and I know that received wisdom says that one shouldn't keep cories in an 8g tank. All things being equal, I'll be getting myself a 20g, at some point in the not too distant future.
In the meantime, this is what I'm working with. I'm going to plant my plants properly, the next time I do a water change (they're currently still in their pots). I want my Brazilian Microsword to grow into a carpet, and it's not going to do that, if I keep disturbing it with a deep gravel clean.
I've been trying to get some decent pictures of my cories, but they're challenging my skills (ie, lack of patience), as a wildlife photographer. Actually, they're not "challenging" them, at all - that would suggest a contest of equals!
