thanks! they've only been together for like 2 days now, but they are getting along wonderfully! at first i was gonna put the black into my 5 gal, but the 10 was perfectly ready, but while the temp was acclimating the reg ocellaris (herbie) was attacking the bag like none other! shaking and running into the bag so hard i could hear it! but then they both got added to the 10 at the same time, and they immediately found each other! they nipped a little bit for the first few minutes, but since then they have been fine!
nope, no substrate! i live in a dorm so i have to move the tank quite a bit, don't wanna stir up a sand bed and cause all sorts of problems! lol
