Our lone male guppy used to hang out with our pygmy cories, hovering over them too when they'd be lazy and in the sand, so cute, but once we got our mini-school of 6 Harelequin Rasboras, he decided to join them. Poor thing he can't keep up with them a lot of the time, but he sure tries! Sometimes he chases after a particular rasbora :P I love that little guppy. We call him Gupp-Gupp.
We got the male guppy for "free" as a fry when we got some pygmy cories; guppies live in that tank too and at the time there were a lot of fry.
Our shrimp will just run over the cories; they don't care :P
Our two panda cories are best buds. They are so goofy and adorable and haha. They're our bumbling weirdos. We had 4, but two died 2 weeks after we got them. We went to get more so they'd be four again so they'd have more to hang out with, and there was ick in the tank. Then we went after it was cured, and they had JUST gotten pandas in and they were looking disheveled and unhappy and some had pieces of tails missing -_- So for now we have our two goofballs
Anyway, I think that is enough for now... I love talking about/writing about our aquatic creatures
