I just now discovered this thread. I'm extremely sorry to hear about your series of events. Dang man... What a rough situation. =\
A few positive and encouraging words though. The tank looks phenomenal. Everyone is spot on when they tell you how gorgeous it is! Such a creative and monolithic set up. You're very good at what you do. And those odd tetras... Try looking up copeland tetras or Hyphessobrycon copelandi. See if that yields anything. You may be able to find them from an online retailer this way. Or check out this site real quick: http://aquavisie.retry.org/Database/...copelandi.html
Best wishes to you when you make your next attempt to get it stocked and thriving again! Don't give up!
