Several weeks ago, I noticed some curious critters appearing in my aquarium; I'd recently ordered some plants from AquaBid, so I suspect they were stowaways (that'll teach me a lesson about washing before planting!). Think you guys can help me identify them?
I couldn't get a very good still picture of the most numerous ones, so here's a brief video of 'em swimming around: click!
I've also found a couple snails, but I'm not entirely sure what type they are--cute fellows, though! They're dark brown in color.
Finally, any idea what this stuff is on my substrate?
I'm not too worried about any of these guys because
a) they only seem to be eating the dead parts of my plants, and
b) I'll be starting a fishless cycle very soon, so I'm guessing a good portion will be KO'd by the ammonia levels.
