The Otos are little crackheads!
Update on the tank and surrounding madness: I changed the lighting on the 10G to just 2 6700K 9W bulbs, one in ea. fixture as per suggestions on plantedtank.net. I finally looked at my heater it was only 25Watts so i added another small one, this is just a temp fix though. But the big news is I have finally started putting together the ikea furniture i took apart to fit the tank in. It involves some custom wood working on my (and my fiance's fathers part) but so far I have the initial mock up...
My fiance is a decorative painter/artist so I will be able to match the new pieces to the existing. Plans include an intigrated light top over the 10G.
First of all, great tank! You've got some gnarly lookin driftwood and I love the guppy grass drapings Once you get that black background, the attention will be focused on what's in the tank and it will look a lot bigger!
About the otos though, I'd keep them in quarantine for at least 4 weeks, you never know what they might be harboring even if they look healthy and active. And I'm sure you don't want to endanger that beautiful betta!
